Physics is about how things move and interact in the world,
from tiny particles to big objects.
Broadly divided into two: Classical and Quantum Physics
Classical physics deals with everyday things we can see and measure,
like how a ball moves or how light travels. Quantum physics, on the
other hand, looks at the behavior of very tiny particles, like atoms and
electrons, which don’t always follow the same rules as bigger objects
Classical physics includes:
1. Mechanics: The study of motion and forces, like how objects
move and interact (e.g., Newton's laws of motion).
2. Thermodynamics: The study of heat, energy, and their
transformations (e.g., laws of heat and energy conservation).
3. Electromagnetism: The study of electric and magnetic fields and
their effects (e.g., electric circuits and magnetic fields).
4. Optics: The study of light and its behavior (e.g., how lenses and
mirrors work).
5. Acoustics: The study of sound and its propagation (e.g., how
sound travels through different materials).
Mechanics: Divided into two components:
Statics: This focuses on objects at rest or in equilibrium. It studies
how forces are balanced and how structures like bridges and buildings
support loads without moving. For example, statics helps us understand
why a book stays on a table without falling.
Dynamics: This deals with objects in motion and the forces causing
that motion. It explores how and why objects accelerate, decelerate, or
change direction. Dynamics is used to analyze everything from a car
accelerating on a highway to the motion of planets.
