In classical physics, the moment of linear momentum about an axis. A point particle with mass m and velocity v has linear momentum p = mv . Let r be an instantaneous position vector that locates the particle from an origin on a specified axis. The angular momentum L can be written as the vector cross-product in Eq. (1) The illustration shows the geometrical meaning of this equation.
