Want this question answered?
Momentum is conserved when two objects collide in a closed system.
Energy is always conserved. The "why" is a bit difficult to understand; according to Noether's Theorem, this is related to the fact that the laws of physics don't change over time. But that's a lot of advanced math. But that's how conservation of energy is derived nowadays.
Well, the Law of Conservation of Mass a.k.a the Principle of Mass/Matter Conservation says that the mass of everything that is closed to all matter and energy will always remain constant over time. ~ You can only tell if mass or matter is conserved by determining if it has a closed system or an open system ~ Mass or matter is only conserved in a closed system because a closed system is a system that cannot exchange matter with its surroundings, so to say that mass or matter is conserved by being "trapped" and will stay constant. I hope this helped!! XD
A closed system
It is conserved because it stays in the system and never leaves. So it will be there forever until you open up the system.

Closed system
In an elastic collision, all initial kinetic energy is fully restored as final kinetic energy. where nothing is converted into noise, heat or any other form of energy. In an inelastic collision, kinetic energy is "lost" to thermal or sound energy.
Conservation of linear Momentum is independent of the coordinate system. It does not matter what coordinates are used. In a closed system, i.e. no external forces, momentum is conserved
the valve transfers the heat to the valve seat (when the valve is closed)
An angular momentum is the vector product which describes the rotary inertia of a system around its axis and is conserved in a closed system.
Conservation energy is energy that is conserved. The energy remains conserved within the unit whether it has been turned off or closed. When the device is turned back on the energy that was contained is released and therefor uses less energy.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
