What is the stopping distance equation?
Stopping distance = thinking distance + braking distance Thinking distance is the distance that you travel in your car from the point of detecting a hazard to the point of beginning to brake or swerve.
How do you find stopping distance in physics?
The calculation for braking distance begins with Newton’s Second Law, F = ma. The weight of the car is found by multiplying its mass by the acceleration from gravity. The force of friction from the brakes is the weight of the car multiplied by the coefficient of friction.
What is stopping 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) the car has a larger mass (eg there are more people in it)
What is the definition of the term braking distance?
noun. the approximate distance a vehicle needs to come to a complete stop after the brakes are applied.
What is the stopping distance GCSE?
Stopping distance = Thinking distance + Braking distance Thinking distance = the distance travelled in the time it takes the driver to react (reaction time) in metres (m) Braking distance = the distance travelled under the braking force in metres (m)
What is the difference between braking distance and stopping 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 distance quizlet?
Braking distance. The approximate distance traveled before coming to a complete stop when the brakes are applied in a vehicle moving at a specific speed.
What is the meaning of braking distance?
What is work done physics GCSE?
Work done is defined as the amount of force needed to move an object a certain distance. In essence, it is a measure of an energy transferred to or from an object which allows it to be moved.
What is meant by braking distance?
braking distance is the distance a vehicle travels in the time after the driver has applied the brake.
What is total stopping distance quizlet?
Stopping distance is the total distance travelled from the point the driver first sees a reason to stop to when the vehicle actually stops.
What is braking distance aceable?
Braking distance is the time it takes for your car to come to a complete stop after you’ve hit your brakes. When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four.
Why is stopping distance important?
Even if you keep a safe stopping distance, without functioning brakes, there’s no guarantee you’ll be able to avoid a collision if something unexpected happens on the road. Your braking distance is the distance it takes for your car to come to a complete stop from when the brake is first applied.
What is work done equation?
Calculating work done To calculate the work done on an object when a force moves it, use the equation: work done = force × distance. This is when: work done is measured in joules (J) force is measured in newtons (N)
What is the equation for work done in physics GCSE?
Work Done = Force x distance moved. _E = F d _ in Nm or Joules. Work is a measure of the energy transferred to an object, as such it can be measured in Joules.
