# Momentum

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Momentum ( $$p$$ or $$\rho$$ (Greek symbol rho) ) (also known as linear motion or translational momentum) of an object is the amount of mass in motion.  Momentum is a vector quantity having magnitude and direction, some of these include acceleration, displacement, drag, force, lift, thrust, torque, velocity, and weight.

### Momentum Formula

$$\large{ p = m v }$$

Where:

$$\large{ p }$$ or $$\large{ \rho }$$  (Greek symbol rho)  = momentum

$$\large{ m }$$ = mass

$$\large{ v }$$ = velocity
