Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken ... to 28 m/s. Calculate the ...

They are afraid to embrace the power of the graph ... to find the acceleration from this distance-time data. Let's go back to our kinematic equation (assuming we start with zero velocity).

With gold medals in three sprinting events at three Olympic Games, Usain Bolt has written himself into the record books as arguably the fastest human of all time ... data so that you can calculate ...

and acceleration = velocity change ÷ time. To find the distance travelled, look at the area under the graph. In the first 10 seconds this is the area of the triangle, ½ × 10 s × 40 m/s = 200 m.
