Revise: Kinematics FormulaeVelocity and displacement include direction. One direction is chosen as positive, so motion or acceleration in the opposite direction is represented by a negative value. For example, if forwards is positive, a vehicle slowing while moving forwards has negative acceleration.
- Revise: Area Under Graphs
The change in position, including direction. On a velocity–time graph it is represented by signed area: area above the time axis is positive and area below it is negative.
