We learned about the conservation of momentum today.
Conservation of Momentum
\( \vec{p}_{tot_i} = \vec{p}_{tot_f} \)
\( \vec{p}_{1_i} + \vec{p}_{2_i} = \vec{p}_{1_f} + \vec{p}_{2_f} \)
\( m_1~ \vec{v}_{1_i} + m_2~\vec{v}_{2_i} = m_1~ \vec{v}_{1_f} + m_2~ \vec{v}_{2_f} \)
Conservation of Momentum
\( \vec{p}_{tot_i} = \vec{p}_{tot_f} \)
\( \vec{p}_{1_i} + \vec{p}_{2_i} = \vec{p}_{1_f} + \vec{p}_{2_f} \)
\( m_1~ \vec{v}_{1_i} + m_2~\vec{v}_{2_i} = m_1~ \vec{v}_{1_f} + m_2~ \vec{v}_{2_f} \)
