# Law of Conservation of Linear Momentum

on . Posted in Classical Mechanics

Law of conservation of linear momentum states if the net external force acting on a system of bodies is zero, then the momentum of the system remains constant.

## law of conservation of linear momentum formula

$$\large{ \overrightarrow{p} = m \; \overrightarrow{v} }$$
Symbol English Metric
$$\large{ \overrightarrow{p} }$$ = linear momentum $$\large{\frac{lbm-ft}{sec}}$$ $$\large{\frac{kg-m}{s}}$$
$$\large{ m }$$ = mass $$\large{lbm}$$ $$\large{kg}$$
$$\large{ \overrightarrow{v} }$$ = linear velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
