Respuesta :

If the work is negative work then the object will loose energy. The gain or loss in energy can be in the form of potential energy, kinetic energy, or both. The work that is done with be equal to the change in mechanical energy or the object.

Yes, It's true that when the work is completed on an object, the thing earnings energy.

When is figure done on object, does it gain energy or lose energy?

Work changes the quantum of mechanical and internal energy held by objects. When work is done on a system or object, energy added thereto. When work is completed by a system or object, it gives number of its energy to commodity differently. Launching a spheroid way a palm puts in a power like an forelimb oscillates onwards.
