What is the rate of change of velocity called?

Explanation:
Acceleration is the rate at which velocity changes over time. Velocity includes both speed and direction, so whenever either one changes—speeding up, slowing down, or turning—the velocity changes and you have acceleration. It’s found by dividing the change in velocity by the time it takes, with units of meters per second squared. For example, if a car speeds up from 20 m/s to 30 m/s in 2 seconds, its acceleration is (30−20)/2 = 5 m/s^2. If it slows down, that’s negative acceleration. Momentum is mass times velocity, not a rate of change, and speed is only how fast something moves, not how its velocity changes.
