Forces for transport
What's the kinetic energy of a car of mass 1000kg when driven at 13m/s?
When a car doubles its speed, its braking distance:
Stays the same
If a car's braking distance at a speed of 32m/s is 96m, what will it be at a speed of 16m/s?
Fuel consumption can increase with underinflated tyres because it:
Reduces wind resistance
Increases the car's speed
