“Where do you see physics in your
daily life?”
Understanding everyday phenomena through basic physical principles
Foundations of Physics in Everyday Living
• 1. Mechanics: Motion and Forces in Daily Life
• Mechanics deals with motion and the forces that cause it. We encounter it constantly:
• Walking and running involve forces between your feet and the ground (Newton’s Third Law:
action–reaction).
• Riding a bicycle uses balance, friction, and rotational motion.
• Driving a car depends on acceleration, braking, and inertia (Newton’s First Law: objects resist
changes in motion).
• 👉 Example: When a jeepney suddenly stops, passengers tend to move forward due to inertia.

• 2. Energy: Powering Everyday Activities
------Energy is the ability to do work, and it comes in many forms:
• Electrical energy powers appliances like electric fans, refrigerators, and phones.
• Chemical energy from food fuels our bodies.
• Mechanical energy is used when lifting objects or riding vehicles.
• 👉 Example: A light bulb converts electrical energy into light and heat.
Foundations of Physics in Everyday Living
• 3. Heat and Temperature: Thermodynamics at Home
• Thermodynamics explains how heat flows and energy is transferred:
• Cooking involves heat transfer (conduction, convection, radiation).
• Refrigerators remove heat to keep food fresh.
• Wearing different clothes affects how your body retains or loses heat.
• 👉 Example: A metal spoon in hot soup becomes hot because of conduction.
Foundations of Physics in Everyday Living
• 4. Waves and Sound: Communication and Entertainment
• Physics explains sound and wave behavior:
• Speaking and hearing rely on sound waves traveling through air.
• Music systems and earphones convert electrical signals into sound waves.
• Cell phones use electromagnetic waves to send messages.
• 👉 Example: Echoes happen when sound waves reflect off surfaces.
Foundations of Physics in Everyday Living
• 5. Light and Optics: Seeing the World
• Light allows us to see and understand our surroundings:
• Mirrors reflect light to form images.
• Eyeglasses correct vision using refraction.
• Cameras capture images through lenses.
• 👉 Example: A straw in water looks bent due to refraction of light.
Foundations of Physics in Everyday Living
• 6. Electricity and Magnetism: Modern Convenience
• Electricity and magnetism are essential for modern living:
• Power systems supply electricity to homes and schools.
• Motors in appliances (like electric fans) use magnetic forces.
• Charging devices rely on electrical currents.
• 👉 Example: A magnet on a refrigerator sticks because of magnetic attraction.
Foundations of Physics in Everyday Living
• 7. Physics in Technology
• Technology is built on physics principles:
• Smartphones use circuits, waves, and semiconductors.
• Transportation (cars, buses, trains) depends on mechanics and energy.
• Medical tools like X-rays and MRI machines use advanced physics.
• Physics is everywhere—it explains how things move, how energy is used, and how we interact with
the world. By understanding its basic principles, we become more aware of our environment and
better equipped to use technology wisely. Everyday living is, in many ways, a direct application of
physics in action.
Understanding Physics as Part of Daily Experiences
• Physics in Everyday Movements
• Physics explains balance, motion, and friction involved
when a person walks or interacts with objects daily.

• Basic physics principles like gravity and Newton’s laws
explain why objects fall and how they move or stay at
rest.
• Physics Enhances Understanding
• Recognizing physics in daily life develops critical
thinking and practical problem-solving skills.
