Question

1. what is the difference between momentum and impulse?

a. momentum is the sum of mass and velocity.
impulse is the change in momentum.
b. momentum is the sum of mass and velocity.
impulse is the rate of change in momentum.
c. momentum is the product of mass and velocity.
impulse is the change in momentum.
d. momentum is the product of mass and velocity.
impulse is the rate of change in momentum.

Explanation:

Momentum \( p = mv \) (mass \( m \) times velocity \( v \)). Impulse \( J=\Delta p \) (change in momentum).

• Option a: Incorrect as momentum is not sum of mass and velocity.
• Option b: Incorrect as momentum is not sum of mass and velocity.
• Option c: Correct as momentum \( p = mv \) (product of mass and velocity) and impulse \( J=\Delta p \) (change in momentum).
• Option d: Incorrect as impulse is change in momentum, not rate of change.

Answer:

C. Momentum is the product of mass and velocity. Impulse is the change in momentum.
