General Science: How Physics Enhances Quality of Life

Vocabulary terms and definitions focusing on the application of physics principles to everyday life, health, safety, and productivity within the Philippine context.

Physics

The branch of science that studies matter, energy, motion, and forces.

Rice Cooker Principle

Based on heat transfer and electrical energy conversion where electrical energy is converted into heat energy to cook rice and the thermostat switches to "warm" once finished.

Electric Fan Principle

Based on motion and energy transformation where electricity powers a motor to rotate blades, increasing evaporation of sweat to make the user feel cooler.

Refrigerator Principle

Relies on thermodynamics and heat transfer where refrigerants absorb heat from the inside and release it outside through coils.

Washing Machine Principle

Utilizes circular motion and centrifugal force to remove water from clothes through a motor-driven rotation.

X-ray Machines Principle

Uses electromagnetic waves that penetrate soft tissues but are absorbed by bones, allowing doctors to diagnose fractures and diseases.

Digital Thermometers Principle

Based on temperature measurement and electronic sensors that detect temperature changes and convert them into a digital display.

Motorcycle Helmets Principle

Relies on momentum and impact force to absorb impact energy during accidents by increasing the time of collision to reduce the force on the head.

Typhoon Monitoring Systems

Uses satellite technology, waves, and meteorology; atmospheric data is gathered by satellites and Doppler radar is used to track storms and rainfall.

Computers and Laptops Principle

Utilizes electricity and semiconductor technology where electrical signals process information and electronic circuits perform calculations rapidly.

Irrigation Pump Principle

Applies fluid mechanics and pressure to move water from rivers and wells to fields, allowing irrigation over long distances.

Factory Machines Principle

Based on mechanics and energy transformation where machines convert electrical energy into mechanical work to increase automation and efficiency.

Power Tools Principle

Utilizes torque and mechanical advantage to perform work more quickly than manual tools, reducing effort and increasing productivity.

Television Principle

Relies on electromagnetic waves and optics to transmit and convert signals into images and sound.

Basketball (Physics Principles)

Involves projectile motion and gravity where the trajectory, force, and angle determine the ball's path into the hoop.

Smartphones Principle

Utilizes electromagnetic waves and electronics, specifically radio waves for communication while electronic circuits process data and images.

Videoke (Karaoke) Principle

Based on sound waves and electricity where microphones convert sound into electrical signals and speakers convert them back into sound.
