* Acceleration is the rate of change of velocity. Velocity is the rate of change of position, and is measured in meters per second (m/s).
* Change means difference. Acceleration describes how much the velocity changes over time. So, acceleration is the change in velocity divided by the time it takes for that change to occur.
* Units reflect the calculation. Since velocity is in meters per second (m/s) and time is in seconds (s), the unit of acceleration is (m/s) / s. This simplifies to meters per second squared (m/s²).
Think of it this way:
* m/s: tells you how fast something is moving.
* m/s²: tells you how much faster something is moving each second.
Example:
Imagine a car accelerating from rest. If its velocity increases by 10 m/s every second, its acceleration is 10 m/s².
