Question 8002
Braking effectiveness increases, among other circumstances, when...
- The tires have greater grip on the road surface.
- The clutch pedal is pressed at the same time as the brake pedal.
- The vehicle's mass is greater, since the greater the mass, the shorter the braking distance.
Show answer and explanation
Correct answer: The tires have greater grip on the road surface.
The better the tires grip the ground, the better they transfer the braking force to the asphalt and the fewer meters the car needs to stop. Greater mass has the opposite effect, because at the same speed the vehicle has more energy and takes more effort to stop.
