Physics - Mechanics - Work and Energy - Conservation of energy - Conservation of Energy

A 5-step lesson. Step 1: 'Law of Conservation of Energy: Energy cannot be created or destroyed, only transformed from one form to another. Total energy in a closed system remains constant.' Step 2: 'In mechanics (no friction): KE₁ + PE₁ = KE₂ + PE₂. Energy at any point equals energy at any other poi
