* Velocity: m/s (meters per second)
* Acceleration: m/s² (meters per second squared)
Here's why:
Velocity is the rate of change of position over time.
* Position is measured in meters (m).
* Time is measured in seconds (s).
Therefore, velocity is measured in meters per second (m/s).
Acceleration is the rate of change of velocity over time.
* Velocity is measured in meters per second (m/s).
* Time is measured in seconds (s).
Therefore, acceleration is measured in meters per second per second, or meters per second squared (m/s²).
Think of it this way:
* Velocity tells you how fast something is moving.
* Acceleration tells you how quickly the speed of something is changing.
Example:
If a car is traveling at 10 m/s and then accelerates at 2 m/s², it means its speed is increasing by 2 meters per second every second.
