📊 Momentum and Conservation

Studio render showing conservation of momentum: BEFORE — 4kg blue trolley moving at 3 m/s hits stationary 2kg red trolley, total momentum 12 kg m/s. AFTER — combined 6kg trolley moves at 2 m/s, momentum still 12 kg m/s. Formula p = mv shown at top.

Figure 1: Conservation of momentum in a collision — total momentum before equals total momentum after
