What is the difference  between Inertial motion and gravitational motion?
817586
The main difference is that inertial motion is constant velocity with no acceleration, while gravitational motion is under constant acceleration.

Mass. I think.Depending on how strong the gravity is your mass changes.

Rotational motion is similar to circular motion, except the object involved is a rigid body in which all points rotate around the center of mass of the object and not around a fixed point.\n\nRotational motion can be pure rotational motion or a combination of translation and rotation.\n\nPure rotational motion is circular movement in which all points in the body move in circles, and that the centers of these circles all lie on a line called the axis of rotation. Pure Rotation is caused by an arrangement called a 'force couple'. This is where two equal and opposite forces act on the object from an equal [perpendicular]distance apart.\n\nTranslation and Rotation is caused by a single force which does not pass directly through the center of mass. The center of mass will move in a straight line, meanwhile, all points of the object will rotate about the center of mass.<

The laws of motion are the same in any inertial frame of reference (moving at constant velocity). Assuming the car is moving at a constant speed in a straight line, the object in motion will be have the same as it does in a frame of reference that is stationary (also inertial as the velocity is at a constant 0).

e, because of the Newton's 1st law: "An object at rest will remain at rest unless acted upon by an external and unbalanced force . An object in motion will remain in motion unless acted upon by an external and unbalanced force". Assuming inertial frame of reference.\nThe object can still have angular acceleration if there are two forces cancelling each other but are applied to an object at different points. \n\nIn real life there is always something that will slow down the object even in space.

Mass is a measure of inertia and hence greater the mass greater is the inertia.\n The 10kg mass will have the greatest inertia....

Inertia applies to all mass. This isn't the best definition but inertia is a bodies resistance to a change in it's motion. When a volleyball is flying thru the air the amount of force necessary to stop it is equal to it's mass times it's velocity. The amount of force it would take to stop a quarter flying thru the air at the same velocity would be a lot less due to it having less inertia. The same applies if the object is sitting still. It will take more or less force to get the object to move depending on what it's inertia is or it's resistance to acceleration you could say.

the body although is one has two velocities one in vertical and other in horizontal direction...the vertical motion is influenced by gravity where as the horizontal is with a constant velocity hence the motion of the body is of two types...const velocity motion, variable velocity motion

The moment of inertia is of rotational kinematics, its formula depends on the object, its axis of rotation, and the mass is involved to.  So that is how it differs.\nYou can find information on inertia here:\nhttp://en.wikipedia.org/wiki/Moment_of_inertia#Torque\nand here is a table of them\nhttp://en.wikipedia.org/wiki/List_of_moments_of_inertia

Mass is the property of an object to resist movement when a force is applied against it.  While it is often measured as weight and the space it occupies as volume; the mass of an object is constant and independent of these two measurements.  Mass is considered the force exerted on an object and that force the object exerts on the universe.  (The Galilean equivalence principle states these two forces are equal, due to our limited understanding of gravity.)\n\nIn a gravitational field the mass is acted upon by the force of gravity (and there is no place in the known universe where the force of gravity doesn't apply).  The mass can be measured by its weight, but the weight changes as the gravity field changes an the mass does not.  The volume of the object can vary independent of the gravity field, but it is not a measurement of mass since it varies with the temperature.  The mass also describes the power due to gravity that the object exerts on other objects.  Until we understand gravity better then the power of gravity imparted to an object by its mass equals that of the gravitational power imparted to other objects by that object.\n\nIn Einstein’s theory of Special Relativity and particle or quantum physics the mass of an object is the same in all frames of reference.\n\nAccording to Wikipedia:  http://en.wikipedia.org/wiki/Mass\n"Mass is a property of a physical object that quantifies the amount of matter and energy it is equivalent to. Mass is a central concept of classical mechanics and related subjects, and there are several forms of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.\n\nIn classical mechanics, there are three types of mass or properties called mass:\n\n-  Inertial mass is a measure of an object's resistance to changing its state of motion when a force is applied. An object with small inertial mass changes its motion more readily, and an object with large inertial mass does so less readily. \n-  Passive gravitational mass is a measure of the strength of an object's interaction with the gravitational field. Within the same gravitational field, an object with a smaller passive gravitational mass experiences a smaller force than an object with a larger passive gravitational mass. (This force is called the weight of the object. In informal usage, the word "weight" is often used synonymously with "mass", because the strength of the gravitational field is roughly constant everywhere on the surface of the Earth. In physics, the two terms are distinct: an object will have a larger weight if it is placed in a stronger gravitational field, but its passive gravitational mass remains unchanged.) \n-  Active gravitational mass is a measure of the strength of the gravitational field due to a particular object. For example, the gravitational field that one experiences on the Moon is weaker than that of the Earth because the Moon has less active gravitational mass.\n\nAlthough inertial mass, passive gravitational mass and active gravitational mass are conceptually distinct, no experiment has ever unambiguously demonstrated any difference between them. This empirical observation leads to the equivalence principle of general relativity. The weak form of the equivalence principle states that this correspondence between inertial and gravitational masses is not accidental, and that no experiment will ever detect a difference between them."\n\nAccording to Wikipedia:  http://en.wikipedia.org/wiki/Invariant_mass\n"The invariant mass or intrinsic mass or proper mass or rest mass or just mass is a measurement or calculation of the mass of an object that is the same for all frames of reference. For any frame of reference, the invariant m

Gravity is the curvature of spacetime encircling around a body with mass.Other bodies move in curved line which is called as orbits.These movement coupled with light rays causes eclipse.

Gravity is proportional to the mass of the planet.  I'd say the acceleration on this planet is 0.1045 * 9.81 m/s^2.  \n\nFor b) use x =  1/2at^2\n\nt = time  \na = acceleration due to local gravity

No. You can understand the difference by going back to its source: the Newton's Second Law.\n\nF = ma\n\nThe weight of an object is the attractive force (F) exercised by the Earth on that object.\n\nAs the above equation shows, the mass (m) of an object is the constant of proportionality that links any force exercised on the object with the consequent acceleration (a).\n\nSo you see that the weight is a special case of force, that you have when a is the Earth's gravity acceleration. \n\nNow suppose you bring the same object on another planet, say Mars, where the gravity acceleration is different. Its mass doesn't change, but the weight does!\n\nThe weight of an object is an Earth accident, while its mass is a more fundamental concept because its value remains constant (at least within the non-relativistic limit, but this is another story).

There are 2 kinds of mass:\n\nGRAVITATIONAL MASS:  The mass you can calculate from Newton's Law of Gravity:  F = G*m1*m2/r^2\nhere m1 and m2 are the gravitational masses of two objects.\n\nINERTIAL MASS:  The mass one can calculate from Newton's 2nd Law of mechanics:  F = m*a\nhere m is the inertial mass of an object.\n\nThey are equivalent (according to Einstein's General Relativity), but it doesn't mean that having one means having the other.  So photons (light) have gravitational mass, but not inertial mass, and so they can travel at the speed of light and at the same time be affected by gravity.\n\nHope I helped.

The force of gravity has to do with an attraction of objects due to mass. The nuclear force has to do with attraction or repulsion of nucleous at very small distances. Electric Force is attraction or repulsion due to the charge of the object, and is very important in the actual structure of an atom. Inertia has to do with the continued movement of an object (an object in motion continues to move unless another force acts upon that object.)\n\nYou might think that gravity is a strong force, because you see it's effects all the time - however, the strongest forces will either be the nuclear force or electric force. If gravity is stronger than electric force, then you get black holes.

According to Special Theory of Relativity, speed of light in free space is same for all inertial observers (inertial observer is an observer possessing a  frame of reference in which Newtons law of inertia is true).\n\nWhen we study General Theory of Relativity, in the context of Cosmology we come across case when Galaxies moving with speed greater than the speed of light. Here Galaxies are beyond the particle horizon. But actually the space between the Galaxies are increasing with speed greater than the speed of light beyond the particle horizon.\n\nTachyons  are not experimentally observed entities and it got imaginary mass as well. Imaginary mass cannot be physically observed.
