What action keeps the tires on the road? friction
What do tire treads have to do with water flow? pushes water away from the tire
What do shock absorbers do? help create traction
A car driven around a curve has a natural tendency to go in a ____ path. straight
The higher your speed, the more _______ is required. traction
perception + reaction + braking distance = ____ total stopping distance
What happens to braking distance as speed doubles? it doubles
What does the 4 second rule mean? its the time it takes you to react to a traffic event
What does the second collision consist of? the occupants hitting the inside of the car after the initial collision
Is a seatbelt and active or passive restraint? active
What is a restraint called that doesnt require the driver to handle it? passive restraint
The point at which all weight is evenly balanced is known as the center of gravity
What does adding weight to the top of a car do to the stability? makes it worse
If a tire is underinflated, the only part that touches the road is the outside edges
tires, shock absorbers, and steering systems all affect traction
