physics in daily life
Answer (1)
Answer:Walking:Friction between your shoes and the ground provides the force that allows you to move forward and prevents you from slipping. Opening a Door:Applying a force to the door handle causes it to rotate around its hinges, a demonstration of torque. Car Seatbelts and Airbags:These safety features utilize inertia to protect occupants during collisions by resisting changes in motion. Bouncing Ball:The upward and downward motion of a bouncing ball is governed by gravity and the elasticity of the ball. 2. Heat and Thermodynamics:Steam Iron:A steam iron uses heat transfer (thermodynamics) to produce steam and iron clothes. Refrigerator:Refrigerators use principles of thermodynamics to maintain a cool temperature by transferring heat away from the interior. Cooking:Various cooking methods, like using a stove or microwave, involve heat transfer and energy conversion. 3. Electricity and Magnetism:Electrical Appliances:Devices like toasters, computers, and televisions rely on electricity and electromagnetism to function. Smartphone:Smartphones use electromagnetism for communication (radio waves, etc.) and touchscreens. Power Generation:The electricity that powers our homes and devices is generated through various physical processes like electromagnetism.
