Acceleration 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 is changing. In other words, it measures how quickly an object is speeding up, slowing down, or changing direction. To calculate acceleration, you can use the equation:
acceleration = (final velocity - initial velocity) / time
where the final velocity is the object's velocity at the end of a certain time period, the initial velocity is the object's velocity at the beginning of that time period, and time is the duration over which the velocity changed.
