Physics Unit 2.1 Forces and braking.

HideShow resource information
Describe the forces when a vehicle is travelling at a steady speed.
The resistive forces balance the driving force.
1 of 7
What are most resistive forces caused by?
Air resistance.
2 of 7
The greater the speed of vehicle...
the greater the braking force needed to stop it. This also increases the stopping distance.
3 of 7
What does the stopping distance equal?
Thinking distance + braking distance.
4 of 7
What affects a driver's reaction time?
Alcohol, drugs, tiredness, and distractions (such as music, and passengers).
5 of 7
What happens when brakes are applied?
Work done by the friction force between the brakes, and the wheel reduces the kinetic energy of the vehicle, and the temperature of the brakes increase.
6 of 7
What can a vehicle's braking be affected by?
Adverse road, weather conditions, and poor condition of the vehicle.
