on the basis of newtons law of gravity what is the instrument made?

If you're talking about the balls swinger, else you'd be talking about the perpetual motion machine.

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.

how about a gyroscope?

Weight is a unit measure of gravitational force.

I think the truest indication of Newton's genius was his discovery (not exactly intuitive) that the same force that causes an object to fall to the ground was none other than the same force that keeps the moon and planets in their orbits.

The answer is C. Although B seems to be a possible answer at first, there could still be an n-number of forces acting on the object such that the sum of all the force vectors is zero, thus making C the more complete answer. One of Newton's laws says that F=m*a (force on an object equals its mass times its acceleration), or a force of 1 Newton on a 1kg object will make it accelerate at a rate of 1m/s^2 in the same direction of the force.

Still more theory than fact.\nIt is responsible for the force of gravity.

Gravity, friction and centrifigul.  Don't forget various applications of force = leverage, pulleys.

depends on the direction of the force

If you know the density of the material, you can measure it's volume.  D = M / V.  Therefore, the mass equals the density of the object times the volume.  The weight of the material is its mass times gravity.

The formula for either is P=rho*g*h, where rho is the density of the material (mass per unit volume) and g is acceleration of gravity, and h is the depth of the material at which you are measuring the pressure. \n\nPressure is a force per unit area. If force are unbalanced, then one gets acceleration of something i.e., something moves, by Newton's second law, F=ma.

I say Newton in about 1700:\n\n"Newton’s form of Kepler’s third law shows that one can use orbital motion to determine the masses of the objects."

The last poster needs to have his dynamic physics retaught, or stop trying to sound like an engineer.\n\nThe first mistake, is identifying newtons = force x distance.  This is actually a measure of work or energy and measured in joules.  The second mistake identifying force as being measured in joules.  Force is measured in Newtons.  Since it was Isaac Newton in the second law of motion that defined Force.\n\nYour question cannot really be answered without more information.  What is the direction of motion, horizontally or vertically?  \n\nVerically?  Then 150 lbs of force.  Pounds were once used to measure force.  If you want to use metric, convert the 150 lbs to kilograms, multiply by 9.8 and then you must exert at least this much force in Newtons to overcome the force of gravity.  150 lbs is 68.04 kg.\n\nHorizontally, what type of surface?  Determine the coefficient of friction, and multiply it by the mass in kilograms.  Then this is the amount of force you need to exert to overcome the force of friction.  There are two types of friction, static and dynamic.  In other words it takes more force to move an object at rest, but once the object is in motion it takes less force to keep it move (opposing the dynamic force of friction).\n\nWatts by the way is a measurement of power, which is energy derived by time, Power = dE/dt.  Joules per second.

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.

Sir Isaac Newton developed the universal law of gravitation.  This law was developed as an inverse square law (1/(r squared) where r is the distance between the two objects.). This law states that all masses are attracted to each other no matter how far away from each other they are.  The key to this law is that the force at which they pull at each other is not only inversely proportional the square of their distance apart but also dependent on their mass.  The equation is as follows:  F=G*((m1*m2)/(r squared) where F is the force created between them, m1 and m2 are the masses in kg of the objects and G is the universal gravitation constant which is 6.642 x10(-11) N M(2)kg(-2) (these last letters are the units it is in.)\nThe Force at which any object on earth has is simply the mass of that object times the acceleration at the surface which is 9.81 m/s(2) this force is the same as if you put the mass of the earth times that objects mass times the gravitational consant then divided by the square of the distance to the center of the earth.\n     As far as I am aware all field forces are inverse square laws which basically means that the closer an objects gets to another the attraction between then increases as the square of the previous force.  The closer they are together the stronger the force.\n     The string theory was devised to explain multiple dimensions and as a way to explain how subatomic particles can seem to be in more than one place at once.  It consists of a tube (string) that has a very small diameter but is infinitely long.  In this theory there are also an infinite number of these strings floating all over invisibly each containg multiple galaxies.  Hope this helps.
