Speed
* Meters per second (m/s): The standard unit in the metric system.
* Kilometers per hour (km/h): Commonly used for road speeds.
* Miles per hour (mph): The standard unit in the US and UK.
* Feet per second (ft/s): Used in some engineering applications.
* Knots (kt): Used for nautical speed (one knot is approximately one nautical mile per hour).
Velocity
* Meters per second (m/s): The standard unit in the metric system. This is the same as speed but includes a direction.
* Kilometers per hour (km/h): Used for road speeds, including direction.
* Miles per hour (mph): Used for road speeds, including direction.
* Feet per second (ft/s): Used in some engineering applications, including direction.
Acceleration
* Meters per second squared (m/s²): The standard unit in the metric system. It represents the change in velocity per second.
* Kilometers per hour squared (km/h²): Less common, but technically possible.
* Miles per hour squared (mph²): Less common, but technically possible.
* Feet per second squared (ft/s²): Used in some engineering applications.
Key Points
* Speed vs. Velocity: Speed is simply the rate of movement. Velocity is speed with a specific direction.
* Acceleration: Acceleration is the rate at which velocity changes. It can be positive (speeding up), negative (slowing down), or zero (constant velocity).
