Question

The work-energy theorem states that the net work done on an object is equal to which of the following?
Options
A Its change in potential energy.
B Its change in kinetic energy.
Correct Answer
C Its change in momentum.
D The power applied to it.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The work-energy theorem is a fundamental principle stating that the net work done by all forces acting on an object (the total work) equals the change in the object's kinetic energy: W_net = ΔKE = ½ m v_f² - ½ m v_i².

Hint

This theorem directly links the concept of work to a change in the energy of motion.
