Very Short Question and Answers - Potential Energy of an Object at a Height

Gravitational potential energy is defined as the work done in raising an object from the ground to a specific height against gravity.

The formula for gravitational potential energy is Ep = mgh.

'm' represents the mass of the object.

'h' represents the height through which the object is raised.

'g' represents the acceleration due to gravity.

The object gains gravitational potential energy.

Work done, W = force × displacement = mg × h = mgh.

Yes, the potential energy of an object can have different values with respect to different ground levels.

No, the work done depends on the difference in vertical heights, not on the path taken.

The potential energy is 588 J.

The height is 4 m.

No, the work done will be the same as long as the height is the same.

The force applied is in the upward direction, against gravity.

Ep = mgh.

An elevated object possesses gravitational potential energy.

The potential energy will also double.

No, Earth's gravitational pull remains relatively constant for heights within the atmosphere.

The gravitational potential energy is converted into kinetic energy.

Potential energy is a scalar quantity.

The potential energy will increase.
