Acceleration is _______________.(1 point) Responses An object’s speed when its motion is constant An object’s speed when its motion is constant An object’s direction’s rate of change An object’s direction’s rate of change An object’s speed in a specific direction An object’s speed in a specific direction An object’s velocity’s rate of change
Acceleration is an object's velocity's rate of change.
Acceleration is defined as an object's velocity's rate of change. To calculate acceleration, you need to determine the change in velocity over a specific time period. Velocity is a vector quantity that includes both speed and direction. Therefore, when an object's velocity changes, it means either its speed or direction or both are changing. Thus, acceleration measures how quickly an object's velocity is changing in terms of speed or direction or both. So, the correct answer is "An object’s velocity’s rate of change."
