Physics Bridge Notes for Class 11
CBSE
These bridge notes will provide a comprehensive overview of key formulas, derivations,
definitions, and laws that are essential for mastering Class 11 CBSE Physics. This guide serves
as a quick reference to help you understand the fundamental concepts and principles.
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)
