B
Speed
C
Displacement
D
Acceleration
Verified step by step guidance1
Understand the definitions of the given quantities: Momentum is the product of mass and velocity, Speed is the magnitude of velocity, and Displacement is the change in position.
Recall that velocity is a vector quantity that describes both speed and direction of motion.
Identify that the rate at which velocity changes with respect to time is a fundamental concept in kinematics.
Recognize that this rate of change of velocity with time is called acceleration.
Therefore, the quantity defined as the rate of change of velocity with time is acceleration.
