- EXPLAINING MOTION- SPEED DISTANCE AND VELOCITY
- distance-time graphs
- gradient of the line = speed
- the steeper the gradient, the quicker the object is travelling
- downhill sections mean the object is returning to its starting point
- displacement-time graphs
- distances are positive or negative
- distance in a given direction from its starting point
- speed = how fast something is moving
- velocity = speed and direction
- negative velocity = object has turned around
