Law of Conservation of Linear Momentum

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	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
