7.1: Linear Momentum
The momentum of a single object is simply the product of its mass and velocity. Suppose we define a physical system that contains several particles which may have different masses and move with different velocities. The total linear momentum of this physical system consisting of (N) particles is the vector sum of the individual linear momenta:
