Physics - Mechanics - Momentum - Collisions (elastic and inelastic) - Types of Collisions

A 5-step lesson. Step 1: 'In ALL collisions: momentum is conserved. m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂.' Step 2: 'Elastic collision: KE is also conserved. ½m₁u₁² + ½m₂u₂² = ½m₁v₁² + ½m₂v₂². Objects bounce apart. For equal masses with one at rest: first stops, second moves at first's original speed.' Step 3:
