* Velocity: Velocity is a measure of how fast an object is moving and in what direction. It is calculated by dividing the change in position (displacement) by the time taken.
* Units of velocity: meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), etc.
* Acceleration: Acceleration is a measure of how quickly an object's velocity is changing. It is calculated by dividing the change in velocity by the time taken.
* Units of acceleration: meters per second squared (m/s²), kilometers per hour squared (km/h²), miles per hour squared (mph²), etc.
The difference in units:
The difference in units comes from the fact that velocity is a measure of distance over time, while acceleration is a measure of change in velocity over time. This means acceleration has an extra "time" component in its units.
