PHY 101 Work, Energy and Power Objective Question
Take CBT

Question

What does the work-energy theorem state?
Options
A Work done is force times distance.
B The work done by the resultant force is equal to the change in kinetic energy of the particle.
Correct Answer
C Power is the rate of doing work.
D Energy cannot be created or destroyed.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The work-energy theorem states that the work done by the net (resultant) force on a particle equals the change in its kinetic energy: W_net = ΔKE = ½mv² - ½mv₀².

Hint

It directly links net work to a change in speed.
