Question

Choose the correct statement:

Statement 1: Momentum is the sum of mass and velocity.

Statement 2: Momentum is the measure of the impact an object will experience in case of a collision.

Statement 3: In a frictionless environment, force is required to maintain a constant velocity.

Statement 4: Momentum is the product of mass and velocity.

• A. All statements are correct
• B. Only statement 4 is correct
• C. Only Statement 2 and 4 are correct
• D. Statement 2,3 and 4 are correct

Answer 1

The correct option is C Only Statement 2 and 4 are correct

Momentum $P$ is the product of mass $M$ and velocity $V$.

$P=MV$

Momentum is the measure of the impact an object will experience in case of a collision. I.e. If two objects are moving at the same speed then the object with the higher mass will cause a greater impact.

In a frictionless environment, application of force changes its velocity. I.e. the body accelerates.
