A Demonstration of Momentum Conservation using Bow, Arrow, and Ballistic Pendulum

The measurement of the variation of the velocity of an arrow $V0$ with the bending of the bow $Δh$ using either a ballistic pendulum or the free-fall phenomenon provided in both cases coinciding linear dependences. These results create the possibility for the utilization of the bow, arrow, and ballistic pendulum for the demonstration and practical exercises of several important physical phenomena. In this paper greatest attention is paid to the demonstration of the momentum conservation principle.
