Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity.

Since the average acceleration is defined as: The slope of the velocity-time graph is the average acceleration. You can see the fitting equation gives an average acceleration of 6 x 10 4 m/s 2.

The gradient or the steepness of the graph can be used to work out the acceleration ... 1700 m. Average speed = total distance ÷ total time = 1,700 m ÷ 50 s = 34 m/s. Look at this velocity ...
