Two objects collide and bounce apart. assuming no outside forces act on the system, which best describes the total momentum after the collision?

C) it is always the same as it was before the collision

Explanation:

Physical properties are properties that can be recognized without bringing upon a chemical change.

An example of a physical property would be the boiling point of a substance.

Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.

An example of a chemical property would be the flammability of a substance.

hope this helps!
