When the breaks are applied to a vehicle the stopping distance is calculated by using a mathematical concept What is that concept?
Thus, the stopping distance is proportional to the square of the initial velocity. Doubling the initial velocity increases the stopping distance by a factor of 4 (for the same deceleration).
How do you calculate stopping distance GCSE?
Stopping distances
- In an emergency, a driver must bring their vehicle to a stop in the shortest distance possible:
- stopping distance = thinking distance + braking distance.
- This is when:
- Reaction time varies from person to person, but is between typically 0.2 s and 0.9 s.
Is stopping distance the same as braking distance?
The braking distance (BD) is the distance the car travels once the brakes are applied until it stops. The stopping distance (SD) is the thinking distance plus the braking distance, which is shown in Equation 1.
What is braking coefficient?
One of the important criteria when evaluating a brake pad is the ‘coefficient of friction’. The coefficient of friction is 0.5. When calculating the coefficient of friction for the braking of a car, the braking torque that occurs when braking, and the fluid pressure that was required to apply the brake pad is used.
How do you calculate braking distance and thinking distance?
For example, if a car doubles its speed from 30 mph to 60 mph, the thinking distance will double from 9 m to 18 m and the braking distance will increase by a factor of four from 14 m to 56 m….
- thinking distance = 21 m.
- braking distance = 75 m.
- total stopping distance = 96 m.
What is braking distance GCSE?
The braking distance is the distance taken to stop once the brakes are applied. The braking distance increases if: the car’s brakes or tyres are in a poor condition. there are poor road and weather conditions (eg icy or wet roads)
How do you calculate stopping distance in kinematics?
The braking distance (BD) is the distance the car travels once the brakes are applied until it stops. The stopping distance (SD) is the thinking distance plus the braking distance, which is shown in Equation 1. We can now get equations for TD and BD using kinematics and Newton’s second law (ΣF = ma).
