* Speed is how fast an object is moving. It's measured in units like meters per second (m/s) or kilometers per hour (km/h).
* Acceleration is the rate at which an object's speed changes. It's measured in units like meters per second squared (m/s²).
Here's the connection:
* Constant speed: If an object is moving at a constant speed, its acceleration is zero.
* Changing speed: If an object's speed is increasing, it's accelerating. If its speed is decreasing, it's decelerating (which is just negative acceleration).
Example:
* A car traveling at a steady 60 km/h has zero acceleration.
* A car speeding up from 0 to 60 km/h in 10 seconds has positive acceleration.
* A car slowing down from 60 km/h to 0 km/h has negative acceleration (deceleration).
To summarize:
* Speed tells you how fast something is moving.
* Acceleration tells you how quickly the speed is changing.
