Law of Conservation of Momentum

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Law of conservation of momentum states that momentum only moves from one place to another, since it is neither created or destroyed.

 

Law of Conservation of Momentum formulas

\(\large{ p = p'  }\)  
\(\large{ m_1  v_1 + m_2  v_2  = m_1  v'_1 + m_2  v'_2  }\)  
\(\large{ \sum m_i v_i = \sum m_i v'_i  }\)  

Where:

\(\large{ p } \) = the system's initial momentum

\(\large{ p' } \) = the system's final momentum

\(\large{ m_1 } \) and \(\large{ m_2 } \) = masses or the object

\(\large{ v_1 } \) and \(\large{ v_2 } \) = velocities of the object

\(\large{ v'_1 } \) and \(\large{ v'_2 } \) = objects velocities after the collision
