1. Physical Quantities
Physics describes natural phenomena using physical quantities.

A physical quantity is a measurable property of a body or system.

Examples:

length
mass
time
temperature
velocity
force

Physical quantities are expressed using a numerical value and a unit.

Example:
5m
10 kg

Types of Physical Quantities
Scalar Quantities

, Scalar quantities have magnitude only.

Examples:

mass
time
temperature
speed
energy

Vector Quantities

Vector quantities have both magnitude and direction.

Examples:

displacement
velocity
acceleration
force
momentum

Formulas

Speed:-
distance/time

Velocity:-
displacement/time

Acceleration:-
change in velocity/ time


2. SI Units
The SI system (International System of Units) is used worldwide for scientific measurements.

Fundamental SI Units

Length – metre (m)
Mass – kilogram (kg)
T ime – second (s)
Temperature – kelvin (K)
