Motion
1 Distance-Time Graphs
1.1 Gradient of line = SPEED
1.2 For an object at a constant speed: SPEED=DISTANCE TRAVELLED/TIME TAKEN.
1.3 Unit of speed is metre/second
1.4 Reading the graph
1.4.1 stationary=horizontal line
1.4.2 accelerating/decelerating=curve
1.4.3 constant speed=diagonal line
2 Velocity and acceleration
2.1 velocity=speed in a given direction
2.2 acceleration=change of velocity per second.
2.2.1 unit is the m/s2
2.3 acceleration=change in velocity/time taken
3 velocity/time graphs
3.1 horizontal line=constant speed
3.2 gradient=acceleration
3.3 area under line=distance travelled
