* Acceleration is the rate of change of velocity. This means it tells us how quickly the speed and direction of an object are changing.
* You need more information. To calculate acceleration, you need to know:
* Initial speed: What was the speed before it increased?
* Time taken: How long did it take for the speed to change from the initial speed to 8 meters per second?
Here's the formula for acceleration:
* acceleration (a) = (final speed (v) - initial speed (u)) / time (t)
Example:
If the object started at rest (initial speed = 0 m/s) and reached 8 m/s in 2 seconds, the acceleration would be:
* a = (8 m/s - 0 m/s) / 2 s = 4 m/s²
