You plot the time it takes for a toy car to travel and then plot a distance time graph. Then repeat at different speeds and compare the different graphs.
Alternatively you could use a ticker tape; this makes a mark every second on the tape, If you attach the car to the end of the tape, its speed will be recorded: distance/dots= speed.
Relationship between Acceleration, Velocity and Time
Speed and velocity are measured in m/s (km/h or mph) and say fast you are going
Speed: how fast without regard to the direction
Velocity: how fast and the direction specified
Average Speed= Distance moved/time taken
Acceleration: how quickly velocity is changing
Acceleration= change in velocity/ time taken
a=(v-u)/t
Velocity Time-graphs
