Speed-time graphs
How do I use a speed-time graph?
-
Speed-time graphs show the speed of an object at different times
-
Speed is on the vertical axis
-
Time is on the horizontal axis
-
-
Straight lines
-
with positive gradients represent objects speeding up (accelerating)
-
with negative gradients represent objects slowing down (decelerating)
-
-
Horizontal lines indicate moving at a constant speed
-
The object is neither speeding up or slowing down
-
If the constant speed is zero, then it at rest
-
Examiner Tips and Tricks
-
Always check the vertical axis to see if you are given a speed-time graph or a distance-time graph!
Worked Example
The speed-time graph for a car travelling between two sets of traffic lights is shown.
For how long was the car travelling at a constant speed?
Constant speed is represented by horizontal lines
There is a horizontal line from 6 seconds to 15 seconds
15 – 6 = 9
9 seconds
