a = (v_f - v_i) / t
Where:
* a is acceleration
* v_f is the final velocity
* v_i is the initial velocity
* t is the time taken
Explanation:
* Acceleration is the rate of change of velocity over time. It tells us how quickly an object's velocity is changing.
* Final velocity (v_f) is the velocity of the object at the end of the time interval.
* Initial velocity (v_i) is the velocity of the object at the beginning of the time interval.
* Time (t) is the duration over which the velocity changes.
Units:
* Acceleration is typically measured in meters per second squared (m/s²).
* Velocity is measured in meters per second (m/s).
* Time is measured in seconds (s).
Example:
If a car starts from rest (v_i = 0 m/s) and reaches a speed of 20 m/s in 5 seconds (t = 5 s), its acceleration would be:
a = (20 m/s - 0 m/s) / 5 s = 4 m/s²
