1.how does inertia affect a person who is not wearing a seatbelt during a collision?
2.how does kinetic energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph?
3.how does kinetic energy affect the stopping distance of a small vehicle compared to a large vehicle?
4.keeping in mind the kinetic energy of a moving vehicle, how can a driver best prepare to enter sharp curves in the roadway?
5.using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuries.

1. Inertia causes the person to be thrown forward when the driver hits the break or when the car is in a collision.
2. Kinetic energy is higher when the velocity is higher so it is more difficult and requires a greater further stopping distance when the vehicle is travelling at 60 mph than at 30 mph.
3. Kinetic energy is higher when the mass is higher so a large and heavier vehicle requires a greater stopping distance than a small vehicle.
4. He can slow down.
5. Because cars colliding in different velocities produced different forces of impact.
