Which measurement relates to the rate of change of velocity?

The measurement that relates to the rate of change of velocity is acceleration. Acceleration is defined as the change in velocity per unit of time. This means that if an object is speeding up, slowing down, or changing direction, it is experiencing acceleration.

To clarify the concept, velocity itself is a measure of how fast an object is moving in a specific direction, but it does not convey any information about how that speed is changing over time. Displacement indicates the change in position of an object and is also not related to how quickly this position change occurs. Jerk represents the rate of change of acceleration, or how acceleration changes over time, but it is a secondary measurement that comes after understanding acceleration. Hence, acceleration is the fundamental measurement that directly correlates with the rate of change of velocity.
