The work-energy theorem states:

A Energy is always conserved

B The net work done on an object equals its change in kinetic energy

C Work equals force times time

D Energy cannot be transferred

✓ Correct Answer: Option B

W_net = ΔKE = ½mv₂² − ½mv₁². Work done by net force changes kinetic energy.

💡 Why is B) the correct answer?

The correct answer to the question "The work-energy theorem states:" is Option B: The net work done on an object equals its change in kinetic energy.

The other options — A) Energy is always conserved, C) Work equals force times time, D) Energy cannot be transferred — are incorrect for this FE Exam Prep question. As explained above: W_net = ΔKE = ½mv₂² − ½mv₁². Work done by net force changes kinetic energy.
