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.

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.
