If two bumper cars collide head-on in a fairground and both cars come to a stop due to the collision, kinetic energy is obviously not conserved. Is momentum conserved even though both cars stop?

Forces, energy and power Forces and the motion of objects can be determined using Newton's Laws of motion. Collisions, explosions and impulse Momentum, kinetic energy and impulse can be used to ...

The kinetic energy of the electrons is related to their binding energy within the solid, while the emission angle corresponds to their momentum parallel to the surface. By varying the photon energy ...
