Natural laws and car control

The force that pulls objects toward the center of the earth is

• Gravity

• Energy of motion

• Kinetic energy

• Inertia

A vehicles speed when going downhill tends to

• Decrease

• Stabilize

• Increase

• Inhibit

Energy if motion is another way of expressing

• Kinetic energy

• Effect of wind on vehicle control

• Mileage rating of a vehicle

• The way vehicle bodies are designed

The gripping action that keeps a tire from slipping on the roadway is called

• Kinetic energy

• Friction

• Gravity

• Inertia

Because if it’s energy of motion, when a vehicle’s speed doubles, the vehicle needs about

• Twice the distance to stop

• Half the distance to stop

• One fourth the distance to stop

• Four times the distance to stop

When braking and turning, you use

• All four tires

• Only the outside edge of your tires

• Split traction

• Additional traction

If a tire is under inflated, the only part that grips the road well is the

• Center of the tire thread

• Outside edges of the tire thread

• Tire cords

• Wear bar

All wheel drive means

• Power is supplied to four wheels

• All four tires are inflated properly

• Your traction is reduced

• Power in the front tires only

Good shock absorbers

• Last for the life of your vehicle

• Decrease available traction

• Are needed only on foreign vehicles

• Help create traction

In wet weather, with temperatures near the freezing point

• A highway roadway freezes before a bridge roadway

• A bridge roadway freezes before a highway roadway

• Bridge and highway roadways freeze at the same time

• Bridge and highway roadways will not freeze
