1 STARTER FIND SOMEONE WHO can answer the questions on your cards get up and move around! Every question must be answered by someone different you are NOT allowed to ask anyone on the same table as you!

2 What are the units of speed when: Distance is measured in metres and time in seconds Distance is measured in kilometres and time in hours Distance is measured in metres and time in minutes

3 Pairs of cameras spot your number plate, start a timer, and then spot your number plate again leaving a zone 800m The speed cameras record that a car takes 350 seconds to move between them. Calculate the average speed of the car. Show your working. Give the unit. 2.28 m/s

4 Distance against time graphs distance time

5 No movement? distance time

6 No movement distance time

7 Constant speed? distance time

8 Constant speed distance time

9 Constant speed distance time The gradient of this graph gives the speed

10 Constant speed distance time How would the graph look different for a faster constant speed?

11 Constant speed distance time fast

12 Constant speed distance time fast How would the graph look different for a slower constant speed?

13 Constant speed distance time fast slow

14 Getting faster? (accelerating) distance time

15 Getting faster distance time

16 Examples distance time

17 A car accelerating from stop and then hitting a wall distance time

18 A car accelerating from stop and then hitting a wall distance time

19 Speed against time graphs speed time

20 No movement? speed time

21 No movement speed time

22 Constant speed? speed time

23 Constant speed speed time

24 Constant speed speed time How would the graph look different for a faster constant speed?

25 Constant speed speed time fast

26 Constant speed speed time fast How would the graph look different for a slower constant speed?

27 Constant speed speed time fast slow

28 Getting faster? (accelerating) speed time

29 Getting faster? (accelerating) speed time Constant acceleration

30 Getting faster? (accelerating) speed time The area under the graph gives the distance travelled

31 Example: speed time

32 A dog falling from a tall building (no air resistance) speed time

33 A dog falling from a tall building (no air resistance) speed time

34 A dog falling from a tall building (no air resistance) speed time Area = height of building

35 Be careful! distance time speed time

36 No movement distance time speed time

37 Constant speed distance time speed time Area = distance travelled

38 Constant acceleration distance time speed time Area = distance travelled

39 Too easy? I have a challenge for you! Can you watch the following video clip and use a stopwatch to determine how far the car travelled? I will provide you with a stopwatch and a table to fill in!

42 Activity Plot these results on a speed time graph, with time on the bottom axis (the x axis) and speed on the side axis (the y axis). Label the points where there is a change in motion A,B,C,D,E,F,H,I,J and K. Example: point A is at time 0 and speed 0.
