Physics Chapter Concepts Quiz

Mass is the measure of the amount of matter in an object, and its S.I. unit is the kilogram (kg).

Vector quantities have both magnitude and direction, such as force and velocity, while scalar quantities have magnitude only, such as mass and temperature.

Hooke's Law states that the extension of a spring is directly proportional to the force applied, within the elastic limit of the spring.
