An object's acceleration is the rate at which its velocity changes over time. It is the rate of change of an object's velocity. Therefore, the correct response is "An object’s velocity’s rate of change."
The correct answer is: An object’s velocity’s rate of change.
Acceleration is defined as the rate at which an object's velocity changes over time. In other words, it measures how quickly an object's speed or direction of motion is changing. When an object's velocity increases, it is said to be accelerating. Similarly, when an object's velocity decreases, it is said to be decelerating or experiencing negative acceleration. Acceleration is a vector quantity, which means it has both magnitude (the numerical value) and direction.
