What is the most common mode of transportation that you might sustain an injury in?
Motor vehichle collisions
100
What is the formula for velocity?
v= d/t
100
What is the formula for momentum?
p = mv
100
State the Law Conservation of Momentum
Total momentum of two colliding objects stays the same after collision
100
Where is/are the crumple zone(s) on a car?
Hood and trunk
200
List 1 serious injury of a collision and 1 minor injury
Serious: Death, head and spinal injuries

Minor: Whiplash, cuts, bruises

200
On a distance/time graph, what does a steep slope indicate?
a fast speed/velocity
200
Define force
A push or pull on an object
200
How do you double momentum?
Double velocity or double mass
200
Where and which way/direction should an infant be seated in a car?
Backwards in the back seat
300
List 1 stimulant and 1 depressant that was discussed in class
S: Caffeine

D: Alcohol

300
What are the two units for velocity or speed?
m/s & km/h
300
What is the unit for momentum?
kg x m/s
300
What is friction?
The force of two objects rubbing together
300
What is one safety feature on the road?
Guardrails, shear pins in light poles
400
Explain reaction time in your own words

The time it takes you to recognize a problem and act on it

400
What is stopping distance?
reaction distance + braking distance
400
What is the formula for impulse?
impulse = Ft
400
What is Newton's First Law of Motion? Give an example
Law of Inertia - coffee in a car spilling forward
400
What are the two different types of seat belts and which one is used today, & why?
2-point and 3-point, we use 3-point because they restrain our upper body, not just our hips
500
What is the legal BAC in Alberta and in Canada?
AB: 0.03

Canada: 0.08

500
What is a rule for following distance? When should you increase following distance?
3-second rule

When it's slippery, icy, raining etc

500
How do you decrease force of a collision?
Increase time
500
Why do two cars with the same mass and speed stop in a head on collision
One is travelling in the positive direction and the other in a negative direction and they cancel out momentums to equal 0
500

What are the three types of safety features on a car?

Restraining, operational, structural
