Questions and Answers

What is the difference between scalar and vector quantities?

Scalar quantities are related to time, while vector quantities are related to space

Scalar quantities have both magnitude and direction, while vector quantities have only magnitude

Scalar quantities are constant, while vector quantities vary with time

Scalar quantities have only magnitude, while vector quantities have both magnitude and direction (correct)

What is impulp in the context of force and motion?

A measure of rotational motion
