Quizplus · Accepted Answer

Scalar quantities are defined by their magnitude alone and do not include direction. Among the options provided, only the mass of a brick (A) is a scalar quantity because it specifies how much matter is in the brick without any direction. Velocity (B), force (C), and acceleration (D) are all vector quantities because they describe both magnitude and direction.
