Acceleration and Velocity-Time Graphs

Acceleration is how quickly the velocity is changing. This can be either a change in speed, change in direction or both.

The formula for acceleration is:

Acceleration = Change in velocity ÷ Time taken

 This is the formula triangle for the equation. The 'v' is the final velocity and the 'u' is the initial velocity. The '(v - u)' means you have to work out the change in velocity.

Acceleration is the change in velocity (m/s) per second (s) which means the unit of acceleration will be m/s².


A dog accelerates from 2 m/s to 6 m/s in 5.6 seconds. Work out
