(1.3-1.5) Speed = Distance / Time

What graph displays information linking speed, distance and time? Name the parts.

A distance-time graph in which the x axis shows time, the y axis shows distance and the speed is shown by the line drawn on the graph.

On a distance-time graph, the steeper the line…

the faster the speed.

On a distance-time graph, what does a horizontal part of a line indicate?

A period of no distance gained, a stop.

On a distance-time graph, how is constant speed represented?

Shown with unchanging gradients of lines.

What formula links speed, distance and time + units?

Speed = Distance / Time

v = s / t (where s stands for spatio meaning space)

m/s or km/h

Detail the experiment investigating the motion of a toy car.

Mark the start and end positions of a measured distance.

Use a metre ruler to measure.

Line up the car with the start position and start stopwatch.

Stop timer when the front of the car passes end point.

Improve- repeat + remove anomalies + average

Calculate average speed using the formula
