For any car travelling at constant velocity the resultant force is on zero.
The braking force needed to stop a vehicle depends on:
- the velocity of the vehicle when the brakes are first applied
- The mass of the vehicle
- The greater the velocity, the greater the deceleration needed to stop it in a certain distance.
- The greater the mass, the greater the braking force needed for a give deceleration.
Thinking distance = the distance travelled by a vehicle in the time it takes the driver to react
Braking Distance= the distance travelled by vehicle during the time the braking force acts
The stopping distance = thinking distance + braking distance
