SUMMARY
Impact velocity is defined as the maximum velocity attained by an object just before it is halted by an external force, resulting in a velocity of zero. It represents the relative velocity between two masses at an infinitesimally small time before they interact. The formula for impact velocity, particularly for two colliding objects, is given by v_{impact} = (m_1v_{1f} + m_2v_{2f})/m_1, where v_{1f} and v_{2f} are the final velocities of the respective masses after collision. This definition clarifies that impact velocity does not necessarily reduce the impacting object's velocity to zero.
