What never changes when two or more objects collide is
A) the momentum of each object.
B) the kinetic energy of each object.
C) the total momentum of all the objects.
D) the total kinetic energy of all the objects.

Question

Quizplus · Accepted Answer

According to the law of conservation of momentum, the total momentum of a system remains constant during a collision, provided no external forces act on the system. Therefore, the total momentum of all the objects involved in a collision remains the same before and after the collision. The momentum of each individual object, however, can change depending on the type of collision. The kinetic energy of the objects, on the other hand, can change during a collision depending on factors such as the mass and velocity of the objects and the type of collision (e.g. elastic, inelastic).
