- Momentum
- Thinking time- time taken to react by a driver
- Thinking distance- distance the car between a hazard appearing and the driver applying the brakes.
- Braking Time- the time taken for the car to stop after the driver has reacted to the hazard.
- Braking distance- diistance the car travels before it comes to a halt whilst the brakes are being applied.
- Braking Time- the time taken for the car to stop after the driver has reacted to the hazard.
- Thinking distance- distance the car between a hazard appearing and the driver applying the brakes.
- Speed and velocity
- Average Speed= Total distance travelled/ Time taken
- Average Speed= 100km/1.25h = 80km/h
- Average Speed= Total distance travelled/ Time taken
- Acceleration= (final velocity-initial velocity)/ time taken
- E.G. v=12m/s u=18m/s t=3s = 12-18/ 3 = -6/3 = -2m/s2
- Motion
- FINAL VELOCITY= INTITAL VELOCITY + ACCELERATION TIME.
- DISPLACEMENT= (INTIAL VELOCITY + FINAL VELOCITY) TIME/2
- DISPLACEMENT= INITAIL VELOCITY TIME +ACCELERATION TIME2/2
- FINAL VELOCITY2= INITIAL VELOCITY2 +2ACCELERATION DISPLACEMENT
- DISPLACEMENT= INITAIL VELOCITY TIME +ACCELERATION TIME2/2
- DISPLACEMENT= (INTIAL VELOCITY + FINAL VELOCITY) TIME/2
- FINAL VELOCITY= INTITAL VELOCITY + ACCELERATION TIME.
- Newton's Laws of Motion
- 1. A body stays at rest or continues at constant speen unless acted upod by an unbalanced force
- 2. Force (N)= mass(kg) x acceleration (m/s2)
- 1. A body stays at rest or continues at constant speen unless acted upod by an unbalanced force
- Momentum(kgm/s) = mass(kg) x velocity (m/s)
- Freefall= 1kg= 10N on Earth
- Acceleration on Freefall= 10m/s2
- Gravitational field strength =10N/kg
- Acceleration on Freefall= 10m/s2
- Thinking time- time taken to react by a driver
- Braking distance- diistance the car travels before it comes to a halt whilst the brakes are being applied.
- Displacement- distance from starting point
- Momentum
- Thinking time- time taken to react by a driver
- Thinking distance- distance the car between a hazard appearing and the driver applying the brakes.
- Braking Time- the time taken for the car to stop after the driver has reacted to the hazard.

- Thinking time- time taken to react by a driver
- Distance is a scalar quantity- it has size only Displacement is a vector quantity- it has size and direction.
