Conservation of Momentum Proof

The video tutorial explains the conservation of momentum by considering a system of particles with external forces. It demonstrates that the integral of net external forces over time equals the change in momentum. If the net external force is zero, the total momentum remains constant, proving the conservation of momentum. The tutorial emphasizes that this holds true only when no net external forces act on the system.
