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
