The speed of the vehicle (the greater the speed the greater the distance before the brakes are applied)
The reaction time of the driver (the slower a driver's reactions the greater the distance travelled before the brakes are applied. Drinking, drugs and tiredness will increase this time)
What can affect the braking distance?
The mass of the vehicle
The speed of a vehicle
The braking force
Fictional forces
What is Newton's first law?
If the forces on an object are balanced then the object remains stationary or at a constant speed
What is Newton's second law?
The acceleration of an object varies directly with the unbalanced force and inversely with its mass
