Physics - Mechanics - Work and Energy - Power - Power in Your Life

Students calculate the power of activities in their own life. Provide example sticky notes: 'Climbing stairs: I weigh ~50kg, stairs are ~3m, takes ~5s → P = 50×10×3/5 = 300W', 'Running 100m in 15s: I need ~500J of kinetic energy → P ≈ 33W (just for KE, more for total)', 'Light bulb in my room: 10W L
