Newton`s Laws
... There are two laws we will use in mechanics that you should be familiar with: the conservation of momentum, and the conservation of energy. Strictly when we say the conservation of momentum, we mean the conservation of linear momentum ( ), the momentum in straight lines. Angular momentum ( ) is also ...
