Week: one

INTRODUCTION TO PHYSISCS

Physics is a branch of science that deals with the study of matter in relation to energy. The branches of

Physics are: Mechanics, Light, Electricity, Waves, Magnetism, Atomic Physics, Electromagnetism,

Dynamics, Heat, Sound etc.

CONCEPT OF MATTER

Matter is anything that has mass or weight and occupies space. The idea that matter is made up of minute

particles called atom dated back to the ancient Greek. Atom is the smallest indivisible Particle of an

element which can take part in a chemical change. It consists of proton, neutron and electron. Proton is

positively charged, neutron is neutral and electron is negatively charged

Matter can exist in three states- Solids, Liquids and Gases

SOLIDS: The molecules of solids are closely packed together. They have definite shape and volume

LIQUIDS: Its molecule are freer than that of solid, they have definite volume but no definite shape

GASES: The cohesive force binding the gases molecules together is negligible. They have no definite

shape and Volume

QUANTITIES AND UNITS

There are two types:

1. Fundamental Quantities

2. Derived Quantities

1. Fundamental quantities and units: These are basic physical quantities or units that are

independent of others and cannot be defined in terms of other quantities or units. Examples of

Fundamental quantities are: Mass, Length, Time, Temperature, Electric Current, Luminous

intensity, Amount of Substance. While Fundamental Unit is given as: Kilogram (Kg), Meter (m),

Seconds (S), Kelvin (k), Ampere (A), Candela (CD), Mole (Mol).
