Ya it actually verifies the Newton's laws.\n\n>> As per Newton's 1st law of motion, an object continues \nto be in its of rest or of uniform motion unless acted \nupon by an external force.\nIn that ad, the objects were in rest but when some object\nacted upon them, they came to motion.

Yes, that is Newton's first law of motion.  Newton's discovery may seem like a no-brainer to you or I, but at that time many people believed that an object fell to the ground because it was attracted to the earth.  His research opened up many new theories and formulas in the field of physics like work, energy, power, momemtum, and acceleration.\n\n#2 - "The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object".  Basically force is equal to mass times acceleration.  F=ma\n\n#3 - "For every action, there is an equal and opposite reaction."  This means when you are leaning against a wall, you're applying 60kg of force against the wall and the wall is applying 60kg of force against you.  Action = Reaction.  When this equation doesn't balance out, something will usually break.

My favourite is the test done to prove the magnetic force of earth.  I do not remember who the scientist was but in the dome of St. Pauls's Cathedral in London UK, he suspended a rope from the highest point down to the ground where he had a level patch of sand.  A weighted point on the rope was just about able to touch the sand.  Sure enough, as time went on the rope began to move with the direction of the earth leaving evidence of stripes in the sand.

begin our explanation of how Newton changed our understanding of the Universe by enumerating his Three Laws of Motion. \n\nNewton's First Law of Motion:\nI. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.  \n\nThis we recognize as essentially Galileo's concept of inertia, and this is often termed simply the "Law of Inertia". \n\nNewton's Second Law of Motion:\nII. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.  \n\nThis is the most powerful of Newton's three Laws, because it allows quantitative calculations of dynamics: how do velocities change when forces are applied. Notice the fundamental difference between Newton's 2nd Law and the dynamics of Aristotle: according to Newton, a force causes only a change in velocity (an acceleration); it does not maintain the velocity as Aristotle held. \n\nThis is sometimes summarized by saying that under Newton, F = ma, but under Aristotle F = mv, where v is the velocity. Thus, according to Aristotle there is only a velocity if there is a force, but according to Newton an object with a certain velocity maintains that velocity unless a force acts on it to cause an acceleration (that is, a change in the velocity). As we have noted earlier in conjunction with the discussion of Galileo, Aristotle's view seems to be more in accord with common sense, but that is because of a failure to appreciate the role played by frictional forces. Once account is taken of all forces acting in a given situation it is the dynamics of Galileo and Newton, not of Aristotle, that are found to be in accord with the observations. \n\nNewton's Third Law of Motion:\nIII. For every action there is an equal and opposite reaction.  \n\nThis law is exemplified by what happens if we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction (leaving us facedown in the water, if we aren't careful!).

Newton's first law states: A object at rest will remain at rest and an object in motion will remain in motion (at a constant speed and direction) unless acted upon by an external force.\n\nThis is also known as the law of inertia.

Newtons law is called the Laws of Motions. There are three laws for it. The first law is known as the  "law of inertia" states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Basically if objects are not at equilibrium they do not accelerate, they only accelerate if there is a net or unbalanced force acting upon it. The second law is mainly about the behavior of objects. That all existing forces are not balance. It states thatacceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The third law is known as " for every action there is an equal and opposite reaction " this basically states that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

The first law of Newton is, “an object is at rest or in uniform motion till a force acts on it”\n\nHence first law tells us what a force is.\n\nA force is one which changes the state of rest or state of uniform speed.\n\nAll the three laws of motion are implicated in the given example.\n\nFirst of all let us assume that the cart with the blocks is moving toward the solid barrier with a constant speed.\n\nThough both the cart and blocks are moving, the blocks are rest with respect to the cart and vice versa.\n\nThe static frictional force between the blocks and cart is preventing the relative motion between the two.\n\nNewton’s first law explains this. \n\nIf there is no frictional force between the two, then there will be relative motion between the two.\n\n Now consider the motion of the two together. Both are moving toward the barrier with constant speed.\n\nThus both will be in a state of constant speed till a force acts on them.\n\n“The cart hits the barrier” means, “The cart exerts a force on the barrier”.\nBy Newton’s third law the barrier exerts an equal and opposite force.\n\nWe are not bothered about what happens to the barrier when the cart exerts a force on the barrier but we are concerned about the reaction force- that is the force exerted on the cart by the barrier.\n\nThe cart comes to rest because of this force. By Newton’s first law the state of motion of the cart is changed to state of rest. \n\nWhen we consider the motion of the block on the cart, initially before the collision of the cart with the barrier, there was no relative motion between the two.\n\nWhen the cart strikes the wall, the speed of the cart is reduced where as the speed of the block is still in the forward motion (toward the barrier).\n\nThere fore, the blocks will move forward toward the barrier. \n\nIf we assume that there is no friction, then the blocks will move forward and hit some portion on the cart and hence their speed is reduced and increased in the opposite direction and they do fell off the cart. This is also due to the external force and is as per Newton’s first law of motion.\n\nIf we take into account the action of force of friction, the situation becomes some what hard to explain in a simple manner.

Newton's third law was the first incarnation of an important principle of physics (still valid of course) called the law of momentum conservation.\n\nIt's regarded as a consequence of other physical laws rather than a postulate as in Newton's theory. In particular it follows mathematically from the assumption that laws of physics are unchanged under translations - that space is homogeneous.\n\nIn Newton's system, the momentum lost/gained by one material object instantaneously appears or disappears in other distant objects. In that sense it's not true except as an approximation because special relativity does not allow anything to propagate faster than the speed of light.\n\nThe modern view is that there's an exchange of momentum between matter and fields rather than directly between matter and matter. The momentum density of the electromagnetic field at each point in space is given by the cross product of the electric and magnetic fields (Poynting vector/c^2):\n\n(1/4pi c)(E x B)\n\nIntegrating the momentum density over space and taking the time derivative gives the total external force (i.e. force due to charged matter) on the electromagnetic field:\n\nF = dP_em/dt = d/dt &#92;integral (1/4pi c)(E(x) x B(x)) d^3x\n\nand there is an equal and opposite force -F (the Lorentz force) on matter due to the electromagnetic field.

Newton believed that gravity acted instantaneously on objects whereas Einstein believed it acted at the speed of light on an object. For instance, if the sun were to disappear suddenly, Newton would predict that all the planets would fly off in straight line paths instantly, whereas Einstein would have predicted that there would have been a lag time for the planets to fly off because nothing can travel faster than the speed of light; including gravity.

By carefully and meticulously studying their orbits and taking note of their positions in the sky night after night for many many years. This work begun with the invention of the telescope but it wasn´t until Johannes Kepler got his hand on all that work, including the work of his mentor Tycho Brahe, that the elliptical nature of planetary motion was discovered. Until then planets were thought to be moving in perfect circles for many resons except scientific. The circle was a nice and harmonic shape. But Kepler, with all those measurments at his hands, couldn´t fit the circle into his charts and models. He thought for years about what other geometrical shapes could fit it and eventually thought to try the ellips. And it fit in (almost) perfectly. From that breakthrough he was able to come up with simple mathematical explanations for planetary motion, now dubbed Kepler´s laws. Isaac Newton later expanded on those laws and the result were Newtons laws. Kepler published his work in 1609 in a book called New Astronomy. (Some errors in Keplers laws could not be explained and corrected until Albert Einstein introduced his work on the space/time relation.)

The study of mechanics concerns the motion of physical bodies and the forces that act upon them. Most people are familiar with systems described by Newtonian mechanics - objects that sit around, move, collide, and are influenced by gravity. Mechanical energy includes things like the kinetic energy of a moving billiard ball, or the potential energy a roller coaster at the top of its track.\n\nThe physics of electromagnetism were not understood at the time of Newton, but in some situations, the mechanics (i.e. the mathematics of motion) of bodies influenced by electromagnetic forces is the same as that of those influenced by gravity. For example, two particles of opposite electrical charge experience an attractive force which is (allowing for certain idealizations) mathematically identical to the gravitational forces two passing planets experience. An electromechanical system might also involve the conversion of mechanical energy into electrical charges or magnetic fields, or vice versa.\n\nEveryday objects are composed of atoms and molecules, which to some degree, are like billiard balls that are constantly bouncing off one another. "Mechanical energy" might include the kinetic energy of these particles, or potential energy stored in the physical arrangement. For example, a compressed solid exerts pressure because electromagnetic forces between particles tend to push them apart. Compressing a solid (moving the particles "uphill" against repulsive electromagnetic forces) stores potential energy in a similar way that pushing a boulder up a hill does (moving the object uphill against the attractive gravitational force of the Earth). On the other hand, a compressed gas exerts pressure because independently moving particles collide with the walls of the container and change direction. The particle is accelerated (its velocity vector changed), and the acceleration times the mass of the particle gives the force applied. Compressing a gas changes the average kinetic energy of the particles, which is reflected in the corresponding increase in the temperature of the gas. The pressure also increases, but this is because the same number of particles have been forced into a smaller volume, so they collide more often with the walls. The force of any given collision is the same, but the number of collisions has increased.\n\nPotential energy does play a role in the pressure of a gas. During an individual collision, a gas molecule comes closer to the molecules of the container wall. The electric fields exert a force on the molecule, slowing it down and reducing its kinetic energy. This energy is temporarily stored as potential energy. Soon, the particle is nearly stationary (if it happened to approach head on), or at least, it is not approaching the wall any more. The electric fields continue to exert a force on the gas molecule. The force continues to change the velocity, and soon the molecule is moving away from the wall and gaining kinetic energy. Generally, the collision is elastic, and all of the kinetic energy is recovered and the particle continues moving with the same speed it had originally.\n\nSolid mechanics studies how rigid bodies behave in response to external forces. Fluid mechanics studies the internal motion of liquids, gases, and other forms of matter. Mechanical energy can be expended in crushing a soda can, affecting the motion and positional arrangement of its component reioufdgkljh kjhfbkjh ael;hgfljh wajh kjfrom the molecules of a solid to the molecules of a liquid when, for example, a glass of water is stirred.\n\nYou could get more information from the link below...

he wrote the three laws of motion .\nJump to: navigation, search\n   Sir Isaac Newton \n\nSir Isaac Newton at 46 in Godfrey Kneller's 1689 portrait. \nBorn \n4 January [O.S. 25 December 1642] 1643\nWoolsthorpe-by-Colsterworth, Lincolnshire, England \nDied \n31 March [O.S. 20 March] 1727\nKensington, London \nSir Isaac Newton, President of the Royal Society, (4 January 1643 – 31 March 1727) [OS: 25 December 1642 – 20 March 1727] was an English mathematician, physicist, astronomer, alchemist, chemist, inventor, and natural philosopher who is generally regarded as one of the greatest scientists and mathematicians in history.\n\nNewton wrote the Philosophiae Naturalis Principia Mathematica in which he described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics. By deriving Kepler's laws of planetary motion from this system, he was the first to show that the motion of objects on Earth and of celestial bodies are governed by the same set of natural laws. The unifying and deterministic power of his laws was integral to the scientific revolution and the advancement of heliocentrism.\n\nAmong other scientific discoveries, Newton realized that the spectrum of colours observed when white light passes through a prism is inherent in the white light and not added by the prism (as Roger Bacon had claimed in the thirteenth century), and notably argued that light is composed of particles. He also developed a law of cooling, describing the rate of cooling of objects when exposed to air. He enunciated the principles of conservation of momentum and angular momentum. Finally, he studied the speed of sound in air, and voiced a theory of the origin of stars. Despite this renown in mainstream science, Newton actually spent more time working on alchemy than physics, writing considerably more papers on the former than the latter24.\n\nNewton played a major role in the history of calculus, sharing credit with Gottfried Leibniz. He also made contributions to other areas of mathematics, for example the generalized binomial theorem. The mathematician and mathematical physicist Joseph Louis Lagrange (1736–1813), said that "Newton was the greatest genius that ever existed and the most fortunate, for we cannot find more than once a system of the world to establish." 20\n\nfor more info go to http://en.wikipedia.org/wiki/Isaac_Newton

Newton set down the 3 laws of motion\n\n1. An object in motion tends to stay in motion in a straight line until it is acted on by a force.(inertia)\n2. Force = mass x acceleration\n3. Every force has an equal and opposite force (jet propulsion)\n\nNewton also discovered that light was made of all the colors of the rainbow. He split light with a prism
