Chapter 9-10-11 Test

A vehicle going uphill works

• with the force of gravity.

• against the force of gravity.

• against centrifugal force

• with centrifugal force.

Good shock absorbers

• last the life of the vehicle.

• decrease available traction.

• are needed only on foreign vehicles.

• help create traction.

An important factor in maintaining traction is

• over inflated tires.

• having a brand new vehicle.

• a clean vehicle.

• good shock absorbers.

The amount of time it takes to identify a hazard, predict a conflict, and decide to brake is your

• perception time.

• reaction time.

• braking time.

• identification time.

A tilting motion from front to back is called

• roll.

• yaw.

• pitch.

• front-tilting.

The force that pulls objects towards Earth is

• gravity.

• energy of motion.

• kinetic energy.

• inertia.

Infants one year old or younger, weighing up to 20 pounds, should be

• carried in a rear-facing child car seat.

• carried in a forward-facing child car seat.

• seat-belted in the back seat.

• seat-belted in the front seat.

The force the keeps a tire from slipping on the roadway is called

• kinetic energy.

• friction.

• gravity.

• inertia.

What keeps a parked car at rest?

• momentum

• friction

• inertia

• gravity

High energy of motion may cause a vehicle

• go around a tight curve successfully.

• miss a tight curve.

• bank a curve.

• maintain a good traction in a tight curve.
