The rate of change of velocity is called what?

Explanation:
The rate at which velocity changes over time is acceleration. Velocity tells how fast something is moving and in what direction, and acceleration is how quickly that velocity changes. If you speed up, slow down, or change direction, your velocity is changing, so you are accelerating. We measure acceleration by how much the velocity changes divided by the time taken, written as Δv/Δt, with units of meters per second squared (m/s^2). For example, if a car goes from 0 to 20 m/s in 4 seconds, its acceleration is 20 m/s divided by 4 s, or 5 m/s^2. Mass is about how much matter an object has (inertia), force is what can cause a change in motion, and friction is a force that opposes motion—none of these are the rate of change of velocity itself.
