PLEASE ANSWER ASAP WILL GIVE BRAINLIEST TO FIRST CORRECT ANSWER. 1. A “conserved quantity” is something that stays the same before and after an interaction. Is the momentum of each object conserved in a collision? Support your answer with data from your simulations.

What is the principle of conservation of momentum?

In physics, the term conservation refers to something which doesn't change. This means that the variable in an equation which represents a conserved quantity is constant over time. It has the same value both before and after an event. There are many conserved quantities in physics. They are often remarkably useful for making predictions in what would otherwise be very complicated situations. In mechanics, there are three fundamental quantities which are conserved. These are momentum, energy, and angular momentum. Conservation of momentum is mostly used for describing collisions between objects. Just as with the other conservation principles, there is a catch: conservation of momentum applies only to an isolated system of objects. In this case an isolated system is one that is not acted on by force external to the system—i.e., there is no external impulse. What this means in the practical example of a collision between two objects is that we need to include both objects and anything else that applies a force to any of the objects for any length of time in the system. If the subscripts i and f denote the initial and final momenta of objects in a system, then the principle of conservation of momentum says
