Laws of Motion

Question:

There are two statements

Statement A : Rate of change of momentum corresponds to force

Statement B : Rate of change of momentum corresponds to Kinetic Energy

Which one of the following is correct?

Options:

A only

B only

Both A and B are correct

Both A and B are wrong

Correct Answer:

A only

Explanation:

We know that F = dp/dt which is the rate of change of momentum with time and KE = p2/2m and hence rate of change of momentum does not corresponds to kinetic energy. Hence choice (a) is correct.
