Acceleration is _______________.(1 point) Responses
An object’s speed when its motion is constant
An object’s speed in a specific direction
An object’s direction’s rate of change
An object’s velocity’s rate of change
An object’s velocity’s rate of change
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 changes over time. Velocity is a vector quantity that defines an object's speed and direction, so acceleration measures how that velocity is changing. To calculate acceleration, you need to determine the change in velocity and divide it by the time taken for that change. The formula for acceleration is:
Acceleration = (Change in Velocity)/(Time taken)
So if you know the initial velocity and the final velocity of an object, you can find the change in velocity by subtracting the initial velocity from the final velocity. Then divide that change in velocity by the time taken for that change, and you will have the acceleration.
