Gravitational Potential Energy Near the Surface of Earth - As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth, g (and hence mg) can be assumed to be constan..

The gravitational force between two particles are equal in magnitude but opposite in directio..

Physicists have categorized all forces occurring in nature under gravitational, electromagnetic, strong nuclear and weak nuclear forces..

When a satellite revolves around the Earth, its centripetal force is provided by the gravitational force of attraction with the Earth. When an electron spins around the nucleus, the centripetal force is provided by the electrostatic force of at..

Let us consider a body of mass 'm' being raised vertically to a height 'h' as in the figure (1). The work done is mgh. Suppose we take the body along the path as in figure (3). The work done during the horizontal motion is zero. Adding up the work done in the two vertical parts of the paths, we get..

Nature of Nuclear Forces - Physicists have categorized all forces occurring in nature under gravitational, electromagnetic, strong nuclear and weak nuclear forces. Both gravitational and electromagnetic forces can be expressed as inverse s..

As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth, g (and hence mg) can be assumed to be constant. Consider a body of mass 'm', lying on the surface of earth at a pl..

Examples of contact forces are frictional forces, normal reaction forces, tensions and forces in collisions. Forces at a distance (non-contact forces) include gravitational forces of attraction between two masses, elec..

Which of the following equations correctly represents the phenomenon of gravitational force (F) if m 1 and m 2 are the masses of the bodies between which the force of gravity exists and d is the distance between them. It is known that F varies directly as the masses an..
