multiple choice
potential energy.
kinetic energy.
a combination of potential energy and kinetic energy.
none of the answers are correct.

Explanation:

According to the work - energy theorem, work done on an object is equal to the change in its mechanical energy (sum of potential and kinetic energy). An increase in potential energy, kinetic energy, or a combination of both requires work to be done on the object.
