Electric fan – Uses electricity (physics) to turn the motor and make the blades spin, moving air. Washing machine – Applies force, water pressure, and motor power (physics and chemistry) to clean clothes.Microwave oven – Uses electromagnetic waves (physics) to heat and move water molecules in food.Opening and closing doors – Involves force and motion (Newton’s Laws). If you push, it moves.Boiling water in a kettle – Involves heat transfer (thermodynamics) where water molecules move faster as temperature rises.
