Displacement or Distance A B Length of journey in meters = Straight line from start to finish in meters = distance displacement

Calculating velocity ,[object Object],[object Object],[object Object]

12.6 10 100 11.0 10 90 9.6 10 80 8.3 10 70 7.1 10 60 6.0 10 50 5.0 10 40 4.0 10 30 2.9 10 20 1.7 10 10 0 0 Start Time to reach this point (seconds) Distance covered (Metres) Timing point (displacement in metres)

What happened? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Velocity/time graphs Velocity Time Velocity changes

Acceleration ,[object Object],[object Object],acceleration final velocity – initial velocity time taken Acceleration =

Velocity Time On a velocity-time graph acceleration is shown by the of the line steepness (gradient)

Velocity Time Highest acceleration? zero acceleration? deceleration?

Vectors and scalars ,[object Object],[object Object],[object Object],vectors scalars

Typical question ,[object Object],(i) Use the figure to determine the velocity of the sprinter after 3 seconds, and identify the period of time when the sprinter’s acceleration was the greatest. (2 marks) (ii) What is happening to the sprinter between 6 and 11 seconds? Explain why this occurs. (3 marks)
