Take two pictures of a vehicle a certain amount of time apart. The position of the vehicle in relation to the distance markings on the road in the 2 pics can be used to calculate the vehicles speed
3 of 11
What is the calculation made to work out the vehicle's average speed?
distance travelled between pictures / time taken between 1st and 2nd picture
4 of 11
Distance = ?
speed x time
5 of 11
What represents the speed on a distance-time graph?
the gradient
6 of 11
Complete the sentence: Increasing the average speed, decreases....
the time taken to travel a certain distance
7 of 11
How do you work out the distance travelled in a certain time if you know the average speed?
(initial speed + final speed / 2) x time
8 of 11
What does a straight line represent on a distance-time graph?
the speed is constant
9 of 11
What does a curved line represent on a distance-time graph?
