Question:

Which one of the following statements concerning momentum is true? Group of answer choices

A. Momentum is a force.

B. Momentum is a scalar quantity.

C. The SI unit of momentum is kg * m^2/s.

D. The momentum of an object is always positive.

E. Momentum and impulse are measured in the same units.

Answer:

Correct answer is E.

Explanation:

A. Momentum is not force, but force is rate of change of momentum, so this statement is wrong.

B. Momentum is a vector quantity, it has magnitude and direction as well.

So statement is wrong.

C. The SI unit of momentum is kg * m/s. Wrong statement.

D. Momentum of object may be negative positive or zero. So statement is correct.

E. Both momentum and impulse has unit kg * m/s. So statement is correct.
