Force during collision
WebBecause contact forces during collisions are so large compared to the inevitable resistance forces such as friction and air resistance, the law of momentum conservation is a great tool for analyzing collisions and providing an accurate estimate of a post-collision (or a pre-collision) speed. In the next part of Lesson 2, the power of this ... WebCars have bumpers designed to protect the body of the car from minor damage during low-speed collisions. In higher-speed collisions, the impact forces will be higher (this comes from Newton's second law—see Additional Background section). The "crumple zone" protects the occupants of the car, because the body of the car itself absorbs the ...

When the two objects collide, there is a force on A due to B— F_\mathrm {AB} F AB —but because of Newton's third law, there is an equal force in the opposite direction, on B due to A— F_\mathrm {BA} F BA. F_\mathrm {AB} = - F_\mathrm {BA} F AB = −F BA
