2
Todays lesson Interpreting distance-time and speed-time graphs

3
A reminder

4
Average speed = distance travelled time taken S t d x

5
Distance against time graphs distance time

6
Lets go on the corridor! Quietly and sensibly! Youll need a pencil and your books

7
Distance/time graph Distance /m 0246810121416 Time (slow)/s Time (fast)/s Distance/m1820222426283032 Time (slow/s Time (fast)/s

8
No movement? distance time

9
No movement distance time

10
Constant speed? distance time

11
Constant speed distance time

12
Constant speed distance time The gradient of this graph gives the speed

13
Constant speed distance time How would the graph look different for a faster constant speed (walking to Physics)?

14
Constant speed distance time fast

15
Constant speed distance time fast How would the graph look different for a slower constant speed (walking to French)?

16
Constant speed distance time fast slow

17
Constant speed distance time fast slow The gradient of the graph gives the speed

18
Constant speed distance time ΔyΔy ΔxΔx Gradient = Δy/Δx

19
Lets go on the corridor! Quietly and sensibly! Youll need a pencil and your books

20
Can you read what Mr Porter has written in your book and then finish the questions you did last lesson? Do now!

21
Distance/time graph - acceleration Distance /m 024681012141618 Time/s Distance/m1820222426283032 Time/s

22
Getting faster? (accelerating) distance time

23
Getting faster (accelerating) distance time

24
Examples distance time

25
A car accelerating from stop and then hitting a wall distance time

26
A car accelerating from stop and then hitting a wall distance time Lets try a simulation

27
Speed against time graphs speed time

28
Speed against time graphs speed time

29
No movement? speed time

30
No movement speed time

31
Constant speed? speed time

32
Constant speed speed time

33
Constant speed speed time How would the graph look different for a faster constant speed?

34
Constant speed speed time fast

35
Constant speed speed time fast How would the graph look different for a slower constant speed?

36
Constant speed speed time fast slow

37
Getting faster? (accelerating) speed time

38
Getting faster? (accelerating) speed time Constant acceleration

39
Getting faster? (accelerating) speed time The gradient of this graph gives the acceleration

40
Getting faster? (accelerating) speed time a = v – u t (v= final speed, u = initial speed) v u The gradient of this graph gives the acceleration

41
Getting faster? (accelerating) speed time The area under the graph gives the distance travelled

42
Example: speed time

43
A dog falling from a tall building (no air resistance) speed time

44
A dog falling from a tall building (no air resistance) speed time

45
A dog falling from a tall building (no air resistance) speed time Area = height of building

46
Be careful! distance time speed time

47
No movement distance time speed time

48
Constant speed distance time speed time Area under graph = distance travelled gradient = speed

49
Constant acceleration distance time speed time Area under graph = distance travelled Gradient = acceleration = a = (v-u)/t

50
Reading – Pages 26 to 29

51
Now lets try some questions! Page 27 questions 2, 5, 6, 7. Page 29 questions 1 & 2.
