In which situation does the reactive force between two colliding objects, cause a physical change?

Answer 1

One situation in which the reactive force between two colliding objects can cause a physical change is in a car crash. When two vehicles collide, the forces exerted on each other can lead to significant physical changes such as deformation of the car's body, breaking of windows, or deployment of airbags. The reactive force generated during the collision transfers energy and momentum, resulting in the physical changes observed after the crash.
