Distance time graphs lesson

Distance and time graph

1. Distance Time Graphs 03/04/2014 Aims To be able to describe what is shown in a distance time graph To be able to draw a distance time graph

2. Time Distance A straight diagonal line shows the object is moving at a constant speed

3. Time Distance A horizontal line shows that the object has stopped moving

4. Time Distance A steeper line shows the object is moving faster

5. Time Distance Diagonal lines going back towards the Time axis show the object is coming closer to its starting position

6. Time Distance A curved line showing an on abject is traveling at increasing or decreasing speed

7. Time Distance Time Distance Time Distance Time Distance Time Distance Time Distance Constant Speed Constant Faster Speed Constant Slower Speed Not Moving Coming Closer Accelerating

8. Time Distance What Does this Graph Show? An object moves at a constant speed from its starting position It stops briefly It moves further away from its starting position at a lower speed It returns to its starting position traveling at a constant speed

9. Time Distance Sketch and give a description of what this graph shows An object starts travelling at a constant speed Its constant speed increases It stops for a while It travels towards its starting point at a constant speed It stops

10. Time Distance Sketch and give a description of what this graph shows

11. Time Distance Sketch a graph to show this description A car sets of at a slow constant speed, it stops briefly to refuel before setting off at a faster constant speed until it reaches its destination. It is stopped for a while before it returns home at a constant speed

12. Drawing Graphs Time (minutes) Distance (m) Include A Title Labels on Each Axis Ensure You Go up in Equal Measurements at Equal distances apart Distance Time Graphs 10 20 30 40 50 60 70 10 20 30 40 50 60

13. Draw a distance time graph for a car which travels at a constant speed for 90 minutes until it is 60 miles from home. It then stops for 30 minutes before traveling for 60 minutes a constant speed covering 30 miles. Time Distance at End of that Time 90 60 30 mins 120 60 60 mins 180 90 So scales of the graph have to go up to 180 for time and 90 for distance

14. Speed = Distance Time Speed Distance Time x

15. Distance Speed x Time A car travelled 2000m in 10 minutes. At what speed was it travelling? Speed = 2000 10 = 200 metres per minute

16. Find the Answer to these Questions A car travelled 500 miles in 10 hours. How fast was it travelling? A car travelled 10,000km in 50 hours. How fast wa s it travelling? How long would it take for a car driving at 50 miles an hour to travel 300 miles? How long would it take a runner running 10 miles an hour to run 30 miles? If a car travelle d for 7 minutes at 400 metres per minute how far will it have travelled? If a person ran for hal f an hour at 200 metres per minute how far would they have run?
