What are two types the momentum?

Question

Gerardo Goodman · Accepted Answer

1. Momentum is the product of a particle's mass and velocity at a given instance.
2. Newton's second law states that force equals momentum rate of change. Force is equal to the product of mass and acceleration for a constant mass.
3. Principle of conservation of linear momentum: If the net external force acting on a system of bodies is zero, then the momentum of the system remains constant.
4. According to Newton's second law

F o r c e = \frac{change in momentum}{t i m e} \vec{F} = \frac{\vec{d p}}{d t}

5. Thus, if

\vec{F} = 0

, then the momentum can be constant or zero.
6. Principle of conservation of angular momentum: Angular momentum of a system is conserved as long as there is no net external torque acting on the system

Angular momentum = radius of the circular path \times linear momentum \vec{L} = \vec{r} \times \vec{p}

7. The rate of change of angular momentum is equal to the torque of the rotational motion.

Torque = \frac{change in angular momentum}{time} τ = \frac{dL}{dt}
