Frequently asked questions
What's the formula?
a = (final v - initial v) ÷ time.
Can a negative acceleration come out?
Yes. It indicates that the speed is decreasing in the range considered.
What units does it use?
m/s for speed, seconds for time, and m/s² for acceleration.
What if the time is zero?
The result cannot be calculated because it would involve division by zero.
