Acceleration is how quickly velocity is changing.
The unit for acceleration is m/s².
To work out acceleration use this:
In order to work out the change in velocity, you need to use this:
Change in velocity = Finishing velocity (m/s) - Initial velocity (m/s)
For example, A skulking cat accelerated from 2m/s to 6m/s in 5.6s. Find it's acceleration.
Answer: Using the formula,
Acceleration = (v - u) / t = (6 - 2) / 5.6 = 4 / 5.6 = 0.71 m/s²
'V' represents the finishing velocity, 'U' represents the initial velocity.
