| The total distance traveled by a vehicle from the moment the driver perceives a hazard until the vehicle comes to a complete stop. | Stopping Distance |
| What is stopping distance? | Stopping distance is the total distance traveled by a vehicle from the moment the driver perceives a hazard until the vehicle comes to a complete stop. |
| The distance a vehicle travels during the driver's reaction time before applying the brakes. | Thinking Distance |
| What is thinking distance? | Thinking distance is the distance traveled by a vehicle during the driver's reaction time, before the driver begins to apply the brakes. |
| The time it takes for a driver to perceive a hazard and react by applying the brakes. | Reaction Time |
| What is reaction time? | Reaction time is the time it takes for a driver to perceive a hazard and react by applying the brakes. |
| Thinking distance is proportional to the speed of the vehicle. | Relationship between Thinking Distance and Vehicle Speed |
| How is thinking distance related to the speed of the vehicle? | Thinking distance is proportional to the speed of the vehicle. |
| Higher vehicle speeds result in longer thinking distances. | Effect of Vehicle Speed on Thinking Distance |
| How does the speed of the vehicle affect thinking distance? | It takes the same amount of time to react, but higher vehicle speeds result in longer thinking distances. |
| The distance traveled by a vehicle from the moment the brakes are applied until it comes to a complete stop. | Braking Distance |
| What is braking distance? | Braking distance is the distance traveled by a vehicle from the moment the brakes are applied until it comes to a complete stop. |
| Braking distance is crucial in emergency stops and determines the total stopping distance of a vehicle. | Importance of Braking Distance |
| Why is braking distance important? | Braking distance is crucial in emergency stops and determines the total stopping distance of a vehicle. |
| Braking distance increases exponentially with increasing speed due to the speed squared relationship. | Exponential Increase in Braking Distance |
| How does braking distance change with changes in vehicle speed? | Braking distance increases exponentially with increasing speed, as it is proportional to the square of the speed. |
| The work done by the brakes of a vehicle to bring it to rest from its initial velocity. | Work Done in Braking |
| What is the work done in braking? | The work done by the brakes of a vehicle to bring it to rest from its initial velocity. |
| The principle stating that energy cannot be created or destroyed, only transferred or converted from one form to another. | Conservation of Energy |
| What does the principle of conservation of energy state? | The principle of conservation of energy states that energy cannot be created or destroyed, only transferred or converted from one form to another. |
| The work done in bringing a vehicle to rest is equal to its initial kinetic energy. | Relationship Between Work and Kinetic Energy |
| What is the relationship between work done and initial kinetic energy in braking? | The work done in bringing a vehicle to rest is equal to its initial kinetic energy. |
| Braking distance can be calculated using the initial kinetic energy of the vehicle and the force exerted by the brakes. | Calculation of Braking Distance |
| How can you calculate braking distance? | Braking distance can be calculated using the initial kinetic energy of the vehicle and the force exerted by the brakes. |
| You can calculate the braking distance of a vehicle if you know its mass, its initial velocity and the force of its brakes. For example, a car of mass 800 kg is travelling at 15 m/s and has brakes that can exert a force of 6000 N. | Example Calculation |
