Distance-Time Graphs - GCSE Physics

This video introduces distance-time graphs. These graphs show how the distance an object has moved varies with time. 

On the x-axis we have time and on the y-axis we have distance. The gradient of a distance-time graph gives the speed of an object. This is because the gradient is given by the change in the y-axis (distance) divided by the change in the x-axis (time). This means that the gradient is the change in distance divided by the change in time i.e. speed.

A steeper gradient means that an object is travelling at a greater speed.
