This Synapse Science resource teaches students to calculate average speed, plot distance–time graphs and describe the motion they show: stationary, constant speed, faster or slower, and returning to ...

Help pupils calculate speed accurately from distance–time graphs and understand why a whole-journey average must include stops. This editable Year 9 maths PowerPoint develops outward and return speeds ...

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...

A distance-time graph shows how the distance travelled by an object changes over time and can be used to calculate the speed of the object. A sloping line on a distance-time graph shows that the ...
