gravitational potential energy animation

Let a body of mass m be at a distance r from a body of mass M. The gravitational potential energy of the mass m is defined as the work done in bringing it from infinity to that point. The work done in moving the mass m through a small distance dr in the gravitatio..

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..

If M is the mass of a body around which a field exists and m is the test mass placed at a distance r from M in this field then, Potential energy per unit mass is gravitational potential (..

Gravitational Potential - The work done in moving a unit mass from infinity to a point in a gravitational field is called the gravitational potential at that point. It is a negative, scalar quantity. The unit is JKg - 1..

Consider an object of mass 'm', raised through a height 'h' above the earth's surface. The work done against gravity gets stored in the object as its potential energy (gravitational potential energy). Therefore, potential energy..

>In a hydro power plant electricity is produced from water. Hydro power plants convert the potential energy of falling water into electricity. Wind Energy Moving air is called wind Wind possesses kinetic energy Wind energy can be used to sail boats,..

Study the following examples - a) Water stored in a reservoir is capable of rotating turbines, which are kept at a lower level i.e, water stored in a reservoir possesses energy. b) If you hit a nail hard with a hammer the nail gets fixed whereas if the hammer is just placed on the nail, t..
