A car travels for at a steady speed of long a straight road. The traffic lights ahead change to red, and the car slows down with a constant deceleration, so that it halts after a further .
Use the graph to deduce the car's deceleration as it slows down.
Important Questions on Describing Motion
A car travels for at a steady speed of long a straight road. The traffic lights ahead change to red, and the car slows down with a constant deceleration, so that it halts after a further .
Use the graph to deduce how far the car travels during the described.



A bus is travelling along a road. It travels a distance of in a time of . The graph shows that the bus's speed is constant.
Explain how you can tell that the bus has no acceleration.

A bus is travelling along a road. It travels a distance of in a time of . The graph shows that the bus's speed is constant.
Copy the graph and shade the area that represents the distance travelled by the bus. Label this area 'distance travelled'.

Here are two graphs that represent the motion of two different objects.
Copy the distance-time graph. Use your graph to explain how you would find the object's speed.

Here are two graphs that represent the motion of two different objects.
The object is moving with constant speed. Explain how you can tell this from the first graph.

Here are two graphs that represent the motion of two different objects.
Copy the speed-time graph. Use your graph to explain how you would find the object's acceleration.
