Key Point of Laws of Conservation of Energy, Momentum and Angular Momentum:

• Momentum is a term in physics; it refers to the amount of motion an object has. The sports team that's on the move has momentum. If the object is in motion (on the move), it has momentum.

• For physics, angular momentum is the rotating equivalent of linear momentum. It is an important quantity for physics because it is a retained quantity the total angular momentum of a closed system remains constant.

Important Topics Covered in Physical Fundamentals of Mechanics IE Irodov:

For physics and chemistry, the Energy Conservation Law states that the total energy of an isolated system remains constant; it is said to have been conserved over time. This law means that energy can not be created nor destroyed; rather, it can only be converted or transferred from one form to another.
