Parts of an investigation

The part of the investigation changed by the researcher

What happens as a result of the manipulated variable

Difference in horizontal position on a graph; x-axis

Difference in vertical position on a graph; y-axis

Steepness of the line on a graph; measured by dividing rise by run

Distance a vehicle travels between when the driver applies the brakes and when the vehicle comes to a stop

Distance that a vehicle travels from the time the driver sees a problem and the vehicle comes to a complete stop

Distance (measured in seconds) at which it is considered safe to follow another vehicle; 2 seconds in good conditions

Measure of an object's motion and likelihood that the object will remain in motion

Any push or pull on an object

Force applied by brakes to stop a vehicle

Force resisting motion, caused by substances rubbing together; rubbing

Force that changes momentum

Total momentum of colliding objects stays the same after the collision

Sum of momentum of colliding objects

Manikins designed to behave like the human body during a collision; fitted with sensors to record data

Parts of a vehicle designed to crush when hit, absorbing much of the energy in a collision; include hood, trunk, and fenders

Hold occupant in place; prevent occupant from hitting the dashboard, windshield, sides, or roof of the car, or from being thrown out of the vehicle during a collision; include seat belts, air bags, headrests, and child seats

Parts of a vehicle that operate all the time to keep occupants safe; include headlights, rear-view and side-view mirrors, tail and signal lights, brakes, etc.

Parts of a vehicle that protect the people inside; include crumple zones and rigid features such as heavy frame, roll cage, and side-impact beams that will not crumple or break under extreme pressure

Traits of a road that are designed to decrease the force of a collision by slowing the impulse

Road feature designed to decrease the force of a collision by slowing the impulse; barrels of water or sand decrease the force of a collision by slowing the impulse and thus absorbing the force of the collision

Road features designed to keep vehicles on the road and to

2-point seat belts; vehicle seat belts designed to hold the occupant in place by securing the person to the seat with a strap placed across the pelvis

3-point seat belt; vehicle seat belt designed to hold the occupant in place by securing the person to the seat with one strap placed across the pelvis and another strap placed across the chest from pelvis to shoulder

Vehicle safety seats designed to raise a child enough to fit the seat belt properly; allow the seat belt to restrain the child during a collision

Inflatable bag instantly released in a collision in order to restrain the occupant and lessen chance of serious injury

First air bag design; inflated too quickly and too much, often causing injury

Inflates more slowly without overinflating

Senses both mass of the occupant and force of collision; adjusts the inflation accordingly
