Gravitational Potential Energy
Gravitational Potential Energy
Gravitational Potential Energy :
The energy possessed by an object due to its height is known as gravitational potential energy. When an object is raised through a certain height above the ground, its energy increases.This is because the work is done on it against gravity while it is moving upwards. Similarly when an object is allowed to fall from higher level to a lower level it gains speed due to gravitational pull, i.e., it gains kinetic energy. Therefore, as the distance of the object from the ground level is increasing, the body is converting its kinetic energy into potential energy. The magnitude of its gravitational potential energy is equivalent to the amount of work done by the weight of the body in causing the fall.

A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.

10thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
