Boyle’s Law
Ohm’s Law
What does the coefficient of friction represent?
A number showing the level of friction between surfaces.
A type of brake pad.
A measure of temperature.
A kind of contamination.
What is the minimum parking brake (handbrake) efficiency required for older vehicles?
At least 16%
At least 58%
At least 25%
At least 10%
For many modern vehicles, what is the required parking brake (handbrake) efficiency depending on design?
25%
58%
16%
40%
Why does mechanical advantage allow for controlled, progressive braking?
Because force is multiplied all at once.
Because force is multiplied gradually, allowing smooth modulation of braking pressure.
Because force is not multiplied at all.
Because braking pressure is always constant.
What must effective braking do to ensure the driver remains in control?
Slow the vehicle without losing balance, grip, or steering ability
Speed up the vehicle while turning
Increase the weight transfer to the rear wheels only
Allow the vehicle to skid for better control
What is essential between tyres and the road for stability and control?
Grip
Air pressure
Paint
Mud
According to the group activity, what should students do after picking a principle?

Present to the class
Create a document or Powerpoint
Take a test
What is the final step in the group activity?
Present to the class
Pick a principle
Research how it is used in the Brake System

Which component in a brake system is responsible for multiplying the force applied by the driver?
Tyres
Brake fluid
Master cylinder
Brake pedal
What effect does a low coefficient of friction between the brake pad and disc have on braking performance?
It increases braking efficiency
It reduces braking effectiveness
It causes the brakes to lock instantly
It has no effect on braking
Why is it important for the parking brake to maintain a minimum efficiency?
To ensure the vehicle can be safely parked on an incline
To improve acceleration
To reduce tyre wear
To increase fuel economy
Which part of the brake system helps transfer force from the pedal to the wheels?
Headlights
Steering wheel
Tyres
Brake fluid
What could happen if the grip between tyres and the road is lost during braking?
The brakes will become more effective
The vehicle will accelerate
The vehicle may skid and lose control
The tyres will inflate automatically
Which law explains how pressure is distributed in hydraulic brake systems?
Pascal’s Law
Archimedes’ Principle
Hooke’s Law
Bernoulli’s Principle
