Chapter 2: Safety Technology

If you are driving down the road, and a vehicle is coming directly at you in your lane, what is best to hit and how should you hit it?

A bush, side swipe

Friction

A force that opposes motion between two surfaces that are in contact

passive restraint

A safety device that does not require vehicle occupants to engage it.

What is an example of a passive restraint?

Airbag

anti-lock braking system

Allows the driver to stop without brake lockup. Standard equipment in many newer vehicles. Designed to be used by applying steady pressure on the brake pedal.

What does ABS stand for?

Anti-Lock Braking System

T/F: Kinetic motion is stationary, not activly moving

False

booster seat

For children less than 8 or under 4 ft 9in

air bags

Increases the impact time and the area over which the resultant force acts, decreasing the pressure and force on the passanger.

What are some examples of active restraints?

Seat belts, infant seat with belt

If you hit a stationary object at 60mph what tends to keep moving forward?

The Car, your body, and the insides of your body (organs)

Inertia

The tendency of an object to resist a change in motion

TCS is?

Traction control System

what is traction control system?

Works in the background to help accelerate and prevent wheel slippage (or "over-spinning") when driving on slippery surfaces.

seat belt

a safety belt used in a car or plane to hold you in your seat in case of an accident

kinetic energy

energy of motion

traction

grip or hold

infant seat

is intended for childern under 20 lbs. it is rear facing and should be placed in the rear of the car

todler seat

is intended for children 20-40 lbs. It is front facing and should be placed in the rear of the car

active restraint

restraint device that you have to engage

Inertia sugests that a body in motion will continue in a __________ line unless some forces act upon it

straight

force of impact

the force with which a moving object hits another object
