* Acceleration is the rate of change of velocity. Velocity is speed in a specific direction.
* To have acceleration, your speed or direction (or both) must be changing.
Example:
* If you're driving at a constant 65 miles per hour in a straight line, your acceleration is 0.
* If you're driving at 65 miles per hour and you step on the gas pedal, you're accelerating (increasing your speed).
* If you're driving at 65 miles per hour and you turn a corner, you're accelerating (changing your direction).
To find acceleration, you need to know:
* Initial velocity: Your speed and direction at the start.
* Final velocity: Your speed and direction at the end of a specific time period.
* Time: The amount of time it took to change your velocity.
The formula for acceleration is:
Acceleration = (Final velocity - Initial velocity) / Time
