Study of motion_______________________________________________________________________________________________________________________________________________________________________________________________________________________12. Uniform linear motion graphs. Distance-time graphs 
We can learn a lot from motion graphs. They can tell us how far something has travelled, how fast it is moving and all the speed changes there have been. Distance-time graphsDistance-time graphs show how far an object has moved at different times.
Imagine a car travelling along a road. We can measure the position of the car (the distance to the origin) every second. Distance and time are recorded in a chart, and used to plot a graph.Line rises 10 m on distance scale for every 1 s on time scale. Steady speed of 10 m/s The same distance travelled in the same time. Speed is constant.
