Ch. 13 Driver's Education Natural Law & Driving

A vehicle's momentum depends on its.....

• kinetic energy

• speed and weight

• center of gravity

• other

If only the outer edges of a tire grip the road.....

• the tire is properly inflated

• the tire is over inflated

• the tire is under inflated

Three factors that affect braking distance are....

• car condition, roadway condition and speed

• steering ability, centrifugal force and ocular tracking

• tread depth, controlled recovery and the motion of energy

One way to stop a skid is to.....

• look for a patch of wet leaves to slow you down

• keep your foot off the pedals and steer into the direction of the skid.

• slam on the brakes

If your car has good directional control. then...

• you can decrease total stopping distance by 3 seconds

• you will be able to keep the car moving in the direction you steer it

• you can make sharp turns at high speeds

After driving through a deep puddle, it is wise to...

• only use engine braking for awhile

• apply light pressure to the brake pedal

• stop at the nearest service station for brake fluid

A power skid occurs when you......

• apply the brakes too hard

• press the accelerator too hard

• downshift too quickly

A driver can turn successfully as long as there is enough...

• friction to overcome centrifugal force

• centrifugal force to overcome friction

• adhesion to overcome friction

Because of inertia.....

• objects at rest move in a straight line

• moving objects continue to move in a straight line

• moving objects continue to move along a curved path

A car's speed and weight both affect...

• the center of gravity

• friction

• force of impact
