Why are seatbelts designed to stretch in a collision?
To decrease the time of collision
What is the kind of collision produces the greatest force of impact?
Head-on collision produces the greatest force of impact.
How does your speed affect a collision?
When traveling at a higher rate of speed you will have more force in case of collision.
What factors do you think may cause there to be a difference between the momentum before and the momentum after the collision?
There is a Law of Conservation of Momentum, which states that total momentum is always conserved. In this case, that means that - assuming no additional bodies are involved - the total momentum before the collision will be the same as the total momentum after the collision. It doesn't even matter whether the collision is elastic or not.
Kinetic energy is the force that needs to be dissipated in a collision?
True

What does an airbag do?
Decreases the force of a collision
What does airbags do?
Decreases the force of a collision
Are they affected in any way after the collision?
Definitely so. Depending on the force of the collision, some may need medical attention. All are required to fill out a police report, and all are sure to be shaken up.
How does your speed affect a collision?
When traveling at a higher rate of speed you will have more force in case of collision.
How do you decrease the amount of force needed to do work?
Decrease friction.

What is a way to prevent injuries in a collision?
Use of a seat belt is a way to prevent injuries in a collision.
What happens when force is decreased?
Assuming that mass stays constant, a decrease in force will result in a corresponding decrease in the acceleration of the object being acted upon by the force.
Kinetic energy is the force that needs to be dissipated in a collision?
True
Is Kinetic energy is the force that needs to be dissipated in a collision?
True
