Chapter 3 Drivers Ed

When you make a controlled stop, the momentum of your vehicle must be overcome by:

The friction force of your brakes The friction force between your tires and the road The compression force of your engine

11. The brake should be pulled all the way up to assure that it is set properly A. True B. False

a

12. Friction is a force caused by the contact of one surface on another. A. True B. False

a

2. When parking and headed downhill, turn your front wheels into the curb. A. True B. False

a

3. The law of inertia means that the objects that are moving tend to continue moving and objects that are not moving tend to remain at rest,unless acted upon by some other force. A. True B. False

a

5. The momentum of an object is proportional to its weight and speed. A. True B. False

a

6. Skidding while braking is caused by the friction of your brakes being stronger than the friction force between your tires and the road, which results in lost of traction. A. True B. False

a

7. The kinetic energy of your moving vehicle determines your ability to stop the car. A. True B. False

a

8. By using __________, all passengers and driver may prevent or limit the injuries that could occur from the effects of inertia. A. seatbelts B. brake C. gears

a

9. Gravity can affect your speed of travel when going uphill and downhill. A. True B. False

a

1. When driving downhill, gravity will cause you to go slower and decrease your stopping distance. A. True B. False

b

10. In the effects of kinetic energy, the slower an object goes, the longer that it will take to bring that object to a stop. A. True B. False

b

4. When parking and headed either uphill or downhill and there is no curb, you______________. A. Turn your front wheels away from the curb B. Turn the wheels so the car will roll away from the center of the road if the brakes fail C. Turn your front wheels into the curb or toward the side of the road
