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?



(a) A only

(b) B only

(c) Both A and B are correct

(d) Both A and B are wrong

​

Answer 1

Answer:

Only A statement if correct.

Explanation:

• According to Newton's second law of motion, force equals the rate of change of momentum. The force operating on a body is represented by the rate of change of linear momentum. So, statement (A) is the correct statement.
• Because momentum is related to velocity, and kinetic energy is proportional to velocity squared, momentum is proportional to the square root of kinetic energy. This indicates that if kinetic energy is quadrupled, momentum will only be quadrupled. So, statement (B) is not the correct statement.
