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 ...

This lesson covers spec points 1.7, 1.8 and 1.9 — plotting and explaining velocity–time graphs, determining acceleration from the gradient, and calculating distance from the area under the graph. • ...

GCSE Physics worksheet on distance-time graphs with answers, covering speed from gradient, horizontal lines, steeper gradients, curved graphs, stopping and restarting, and interpreting journeys.
