Motion
1 Distance Time Graphs
1.1 The gradient of the line on a distance-time graph represents the objects speed
1.2 The steeper the line on a distance-time graph the greater the speed it represents
1.3 Speed (m/s) = Distance travelled (m) / Time taken (s)
2 Velocity And Acceleration
2.1 Velocity is speed in a given direction
2.2 Acceleration is the change of velocity per second
2.3 a = v - u t
3 Velocity-Time Graphys
3.1 If the line on a velocity-time graph is horizontal, the acceleration is zero
3.2 The gradient of a velocity-time graph represents acceleration
3.3 The are under the line on a velocity is the distance travelled
4 Using Graphs
4.1 The speed of an object is given by the gradient of the line on its distance-time graph
4.2 The acceleration of an object is given by the gradient of the line on its velocity-time graph
4.3 The distance travelled by an object is given by the area under the tine of its velocity-time graph.
