Question

unit test: forces and motion
how is acceleration calculated?
acceleration equals the change in velocity divided by time.
acceleration equals speed multiplied by time.
acceleration equals velocity.
acceleration equals distance divided by time.

Explanation:

Acceleration is a measure of how quickly velocity changes. The formula for acceleration $a$ is $a=\frac{\Delta v}{\Delta t}$, where $\Delta v$ is the change in velocity and $\Delta t$ is the time - interval.

Answer:

Acceleration equals the change in velocity divided by time.
