3. SPEED-TIME GRAPHS 01

4. Speed-time graphs are very useful when describing the movement of an object. We can use them to determine whether or not the object is moving at any point in time. We can also use them to see what speed the object is travelling at that point in time.

5. Using data from the graph, we can calculate any acceleration, the change in speed and the change in time. We can also use graphs to calculate distance travelled. The area under a speed-time graph represents the distance travelled.

6. A horizontal line on a speed-time graph represents a constant speed The time is continuously changing but the speed remains constant speed (m/s) time (s)

7. the line on the graph is straight but sloped The line goes through the origin speed (m/s) time (s)

8. speed (m/s) time (s) The steeper the slope of the line the greater the acceleration The object is speeding up

9. The speed increases with decreasing amount speed (m/s) time (s)

10. the line on the graph is straight but sloped speed (m/s) time (s)

11. DISTANACE-TIME GRAPHS 02

12. A distance-time graph shows how the distance and speed of an object changes with time. A straight line indicates constant speed, whereas changes in slope at different time intervals indicate changing speeds.

13. Distance-time graph can be useful in the following ways:   It tells the position of the body at any instant of time.  (ii) The distance covered by the body during a particular interval of time can be seen from the graph.  (iii) The velocity of the body at any instant of time can be determined.

14. A horizontal line on the distance-time graph represents an object or body at rest. distance (m) time (s)

15. the line on the graph is straight but sloped The line goes through the origin distance (m) time (s)

16. distance (m) time (s) The object is speeding up

17. The speed increases with decreasing amount distance (m) time (s)
