Study Notes
Physics Fundamentals
- Physics is the branch of science that studies matter and energy, exploring their interactions and the fundamental laws that govern these phenomena.
Unit of Force
- The primary unit of force in the International System of Units (SI) is the Newton (N). It is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
Gas Laws
- Boyle's Law describes the relationship between pressure and volume for a gas at constant temperature, stating that the pressure of a gas increases as its volume decreases and vice versa.
Speed of Light in Vacuum
- In a vacuum, the speed of light is approximately 299,792 kilometers per second (km/s), which is a fundamental constant of nature denoted as "c".
Archimedes' Principle
- Archimedes' Principle explains how a floating object displaces an amount of fluid equal to its weight. This principle is crucial in understanding buoyancy and the behavior of objects in fluids.
Fundamental Branches and Concepts of Science
- Physics is the branch of science focused on the study of matter and energy, exploring their interactions and the fundamental forces of nature.
Key Units and Measurements
- The primary unit of force in the International System of Units (SI) is the Newton (N).
Gas Laws
- Boyle's Law describes the relationship between pressure and volume for a gas at constant temperature, stating that pressure increases as volume decreases.
Constants of Nature
- In a vacuum, the speed of light is approximately 299,792 kilometers per second (or about 186,282 miles per second).
Principles of Buoyancy
- Archimedes' Principle explains how a floating object displaces an amount of fluid equal to its weight.
Inertia and Motion
- The concept of inertia explains that objects tend to maintain their state of motion unless acted upon by an external force.
Light Refraction
- Refraction is the phenomenon that describes how light bends when it transitions between different media, such as air to water.
Potential Energy
- Potential energy is the type of energy stored in an object due to its position or arrangement in a gravitational or electric field.
Conservation of Energy
- The law of conservation of energy states that energy cannot be created or destroyed; it can only be transformed from one form to another.
Power Measurement
- Power refers to the rate at which work is done or energy is transferred, typically measured in Watts (W).
