Chapter 3: Natural Forces Effecting the Automobile

True or False: Low gears are used to overcome gravity while driving uphill and downhill

True

True or False: 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.

True

True or False: The kinetic energy of your moving vehicle determines your ability to stop the car.

True

True or False: When driving downhill, gravity will cause you to go slower and decrease your stopping distance.

False

True or False: Friction is a force caused by the contact of one surface on another.

True

When parking and headed downhill, turn your front wheels into the curb.

True

True or False: Considering the effects of kinetic energy, the slower an object goes, the longer it will take to bring that object to a stop.

False

Using __________, prevents or limits the driver and passengers injuries that could occur from the effects of inertia.

Seat belts

When parking and headed either uphill or downhill and there is no curb, you______________.

Turn the wheels so the car will roll away from the center of the road if the brakes fail

When parking and headed uphill, turn your front wheels toward the curb and set the parking brake.

False

True or False: Gravity can affect your speed of travel when going uphill and downhill.

True

True or False: The momentum of an object is proportional to its weight and speed.
