MOTIVATION
Look around you!
Almost everything you use today involves physics.
Examples:
Turning on a light
Using a cellphone
Riding a bicycle
Cooking food
Question:
How do you think physics
helps us in our daily lives?
Scientific Foundation
Physics is a fundamental science that studies matter,
energy, motion, and forces. It provides the foundation for
understanding how the universe works, from the smallest
particles to the largest cosmic structures. Physics helps
explain natural phenomena through observation,
experimentation, and logical reasoning.
Laws of Motion
The laws of motion describe how objects move
and interact with forces. These principles
explain everyday actions such as walking,
driving, and throwing objects. Understanding
motion helps connect theory with real-world
experiences.

PHYSICS AROUND US
Physics is present in many activities we do every day.
Examples:
Transportation
Motion of vehicles
Friction between tires & road
Applications of Physics in Everyday Life
Transportation
Cars, airplanes, and space travel rely on
physics.
Energy
Concepts
Energy is the ability to do work and
cause change. Physics explores different
forms of energy, including kinetic,
potential, and thermal energy. These
concepts explain how systems function
and transform over time.
Thermodynamics (Heat and Energy Transfer)
Thermodynamics studies heat, energy
transfer, and how they affect matter. The
Laws of Thermodynamics include:
Energy cannot be created or destroyed,
only transferred.
The entropy (disorder) of an isolated
system always increases.
Absolute zero (-273.15°C) is the lowest
possible temperature.

Examples:
Applications of Physics in Everyday Life
Energy Production
Solar panels, wind turbines, and nuclear
reactors use physics.
Forces and Interaction
Forces cause changes in motion and shape.
Gravity, friction, and magnetism are examples of
forces studied in physics. These interactions help
explain balance, movement, and structure in
nature.

PHYSICS &
SAFETY
Physics helps keep people safe.
Examples:
Seatbelts in cars
Helmets for protection
Proper lifting techniques
Safety equipment in construction
These are based on force, motion, & impact.
Waves and Sound
Physics studies waves as carriers of energy and
information. Sound and light waves affect
communication and perception.
Understanding waves helps explain hearing,
vision, and modern technologies.
Applications of Physics in Everyday Life
Medical Science
X-rays, MRI machines, and radiation
therapy use physics principles.
Electricity
Basics
Electricity plays a major role in modern
life. Physics explains how electric
charges move and interact. This
knowledge supports the development of
electronics, power systems, and
communication devices.

PHYSICS AROUND US
Physics is present in many activities we do every day.
Examples:
At Home Technology
Electricity powering appliances
Heat used in cooking
Smartphones
Television
Internet communication
in daily life
IN HOUSEHOLD ACTIVITIES
Physics principles are used in:
These appliances work because of electricity, energy, and motion.
Applications of Physics in Everyday Life
Technology
Smartphones, computers, and lasers work
because of physics.
Matter Structure
Physics examines the structure of matter at atomic
and subatomic levels. Understanding particles and
forces reveals how materials behave and interact.
This knowledge supports innovation in science and
technology.
Scientific Thinking
Physics encourages critical thinking and
problem solving. It teaches how to analyze
situations logically and test ideas through
experiments. These skills are valuable beyond
science.
Physics in
Life
Physics is present in everyday life, from
technology to natural events. It helps
people understand the world more
clearly and inspires curiosity about how
things work.

WHY IS PHYSICS IMPORTANT?
Physics helps us:
Understand how the world works
Develop technology and machines
Improve health and safety
Make everyday tasks easier and more efficient
Physics plays an important role in modern life.
