Today's Physics learning in Sigma One :)

CHAPTER ONE : INTRODUCTION TO PHYSICS

1.1  Understanding Physics

What is physics ?

• ·         The word Physics is originated from the Greek word
• ·         
• In physics, we study natural phenomena and the properties of matter. The aim of physics is to explain the fundamental nature of the universe by using the concept of physics.
• ·        
• Physics involves the conduct of studies and experiments to find answers to the question in relation to the mysteries of the universe.
• ·         
• The majority of natural phenomena can be explained using the principle of physics :

                i) We cannot see an object behind a wall because light travels in a straight line.

                ii) The image of the pencil formed by the mirror is due to the reflection of light.

Fields of study in physics

1) Forces and pressure - pressure, pressure in liquids, gas pressure, atmospheric pressure, Pascal

                                          principle, Archimedes principle, Bernoulli principle.

2) Heat - studies the influence of heat on different types of matter.

3) Electricity and electromagnetism - Investigate the interaction of electric and magnetic fields.

4) Electronics - studies the use of electronics devices in various fields.

5) Waves - understand the properties of different types of waves and their uses.

6) Light - explain the different phenomenon due to light.

7) Force and motion - investigate the action of force and motion.
