They are often referred to as the SUVAT equations, where "SUVAT" is an acronym from the variables: s = displacement, u = initial velocity, v = final velocity, a = acceleration, t = time.

What is the suvat equation used for?

The SUVAT equations are used when acceleration is constant and velocity is changing. If speed is constant, you can use the speed, distance and time triangle. They can be used to work out initial and final speed, time, dispacement and acceleration, if at least three quantities are known.

How does suvat calculate distance?

Secondly, the displacement or how far the ball travelled will be given by SUVAT equation 2. Again the initial velocity is 0 and the time is 4. This time final velocity is 26.8. It follows that the distance travelled is S = ( 0 + 26.8 2 ) × 4 = 53.6 metres.
