The graph shows the speed of a car in the first few seconds of its journey.
From the graph, it can be seen that the car travels ..........................................
at constant speed and then stops.
at constant speed and then slows down.
with constant acceleration and then at constant speed.
with constant acceleration and then stops.
The speed-time graph is for an objects moving with constant acceleration.
How far does the object move in 20 s?

Which equation can be used to calculate an average speed?
Average Speed = Acceleration/Time
Average Speed = Distance/Time
Average Speed = Distance x Acceleration
Average Speed = Distance x Time
