MS-PS2-1: Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.
I can explain how forces affect objects when they collide and use that knowledge to solve a problem.
When two objects collide, they exert equal and opposite forces on each other.
Collisions can change an object's motion.
Engineers design solutions to reduce the effects of collisions.
Newton's Third Law helps explain collisions.
Seat belts, airbags, and crumple zones are designed using what scientists know about forces during collisions.
Helmets and protective equipment help reduce the forces your body experiences when you fall or collide with another player.
Understanding collisions helps engineers design helmets and other safety equipment that protect riders.
Engineers use collision testing to make vehicles safer for drivers and passengers.
