Forces and Braking 0.0 / 5 ? PhysicsForcesGCSEAQA Created by: LSmithCreated on: 25-03-14 20:18 The stopping distance of a car depends on two factors... thinking distance and braking distance 1 of 12 Under normal driving conditions, the thinking and braking distance depend on... the speed of the car 2 of 12 When a vehicle travels at a steady speed the driving force from the engine is balanced by... air resistance and other resistive forces 3 of 12 For a vehicle to slow down, one or both of the following have to happen... the driving force from the engine must be reduced or the resistive forces must be increased 4 of 12 The thinking distance increases if the _________ increases Reaction time 5 of 12 Reaction time increases if the driver is... -tires -distracted -under the influence of alcohol/drugs 6 of 12 The braking distance is... the distance taken to stop once the brakes are applied 7 of 12 The braking distance increases if... -the car's brakes/tyres are in bad condition -the road and weather conditions are poor 8 of 12 The braking distance also increases as the __________ increases Car’s speed 9 of 12 When the brakes are applied, ________ by the friction force between the brakes and the wheels Work is done 10 of 12 When the brakes are applied and work is done, it ______ the kinetic energy of the vehicle Reduces 11 of 12 When the brakes are applied and work is done, it ______ the temperature of the brakes Increases 12 of 12
