JSS 1: INTRODUCTION TO BASIC PHYSICS

Physics is a branch of pure science that deals with the study of matter, energy, motion, forces and how they interact with one another.

Physics helps us to understand many things that happen around us, such as why objects fall to the ground, how vehicles move, how light travels, how electricity works and how sound is produced.

A person who studies physics is called a physicist.

Branches of Physics

Physics is divided into several major branches. They include:

1. Mechanics

2. Waves

3. Optics

4. Nuclear Physics

5. Electromagnetism

6. Thermodynamics

Mechanics:

Mechanics is the study of the motion and rest of objects and the forces acting on them.

Waves:

Waves is the study of how energy moves from one place to another.

Optics:

Optics is the study of light and how it behaves.

Nuclear Physics: 

Nuclear physics is the study of the nucleus of an atom and its energy.

Electromagnetism:

Electromagnetism is the study of the relationship between electricity and magnetism.

Thermodynamics:

Thermodynamics is the study of heat, temperature and energy changes.

Importance of Physics

1. Physics helps us understand how and why natural phenomena occur.

2. Physics provides knowledge for developing modern technology.

3. Physics helps us understand our surroundings and the natural environment.

4. Physics contributes to the development of phones, radio, television and satellite systems.

5. Physics helps in designing and developing cars, aeroplanes, trains and ships.

6. Physics contributes to the development of medical equipment such as X-ray and ultrasound machines.

7. Physics helps us understand how electricity is generated, transmitted and used.
