Question

Workdone on an object to bring it to a certain point in space is called

Options

A) Gravitational potential energy

B) Potential energy

C) Kinetic energy

D) Mechanical energy

The correct answer is A.

Explanation:

Gravitational potential energy is the energy an object possesses because of its position in a gravitational field. Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. (i.e, P.E\(_g\) = ωh, where ω = mg)
