In a horse-drawn buggy, the friction between the braking system and the wheel surface transformed the energy of the moving buggy into what kind of energy?

• Frictional energy

• Heat energy

• Mechanical energy

• Chemical energy

Technician A says that in a traction control system, the control unit can independently apply individual brake units even though the driver is not stepping on the brake pedal. Technician B says that a vehicle equipped with ABS can automatically reduce engine torque if the wheels are skidding. Who is correct?

• Tech A

• Tech B

• Both Tech A and B

• Neither Tech A or B

• One

• Two

• Three

• Four

Technician A says that the heavier the vehicle, the more stopping power is needed. Technician B says that the faster a vehicle is moving, the more braking power is needed. Who is correct?

• Tech A

• Tech B

• Both Tech A and B

• Neither Tech A or B

Technician A says that vehicles are equipped with a single braking system called a service brake. Technician B says that service brakes have two main sections: the brake assemblies at the wheels and the hydraulic system that applies them. Who is correct?

• Tech A

• Tech B

• Both Tech A and B

• Neither Tech A or B

Kinetic energy is defined as energy of an object in:
