Average velocity is the rate of change of
Correct answer: C. Displacement
- A. Speed
- B. Torque
- C. Displacement
- D. Velocity
Explanation
Average velocity is defined as the total displacement divided by the total time taken. Displacement is a vector quantity that considers both magnitude and direction, making it the correct answer. Speed is a scalar quantity and does not involve direction, which is necessary for velocity calculations. Torque is related to rotational forces and not directly relevant to linear motion. While velocity is indeed the rate of displacement, the question specifically asks for what average velocity is the rate of change of, which is displacement.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
