What term describes the rate of change of an object's displacement per unit time?

The term that describes the rate of change of an object's displacement per unit time is velocity. Velocity is a vector quantity, which means it has both magnitude and direction. It is calculated by taking the change in position (displacement) over the time interval during which that change occurs.

Understanding velocity is crucial in various contexts, especially in forklift operation, as it helps operators gauge how quickly they are traveling with the load and how to navigate safely in an environment where space and timing are critical.

Momentum, while also a fundamental concept, refers to the product of an object's mass and its velocity and does not specifically describe the rate of change of displacement. Force is a physical interaction that changes the state of motion of an object, while displacement is the distance and direction of an object's change in position. Both force and displacement are related to motion but do not specifically address the rate of change over time as velocity does.
