SUMMARY
The discussion focuses on proving that a perfectly inelastic collision results in a greater loss of kinetic energy compared to a partially inelastic collision. The conservation of momentum equations are provided for both scenarios: for perfectly inelastic collisions, the equation is \(P_{inelastic} : m_1v_{1i} + m_2v_{2i} = (m_1 + m_2)v_f\), while for partially inelastic collisions, it is \(P_{partial} : m_1v_{1i} + m_2v_{2i} = m_1v_{1f} + m_2v_{2f}\). The kinetic energy formula \(KE = \frac{1}{2}mv^2\) is essential for comparing energy before and after the collisions.
