Question

the work-energy theorem states that the work done on an object is equal to a change in which quantity?
kinetic energy

displacement

potential energy

mass

Explanation:

The work - energy theorem is a fundamental concept in physics. It states that the net work done on an object is equal to the change in its kinetic energy, mathematically expressed as $W=\Delta KE = KE_{final}-KE_{initial}$. Displacement is a measure of position change, potential energy change is related to work done by conservative forces (not the general work - energy theorem for net work), and mass is a property of matter that doesn't change with work done on the object.

Answer:

A. kinetic energy
