Elements of physics

1. Introduction to Physics
Presented by
Dr. Sumi Sarma

2. PHYSICS is the study of nature in an
attempt to understand how the universe
behaves.
Physics aims to describe the functions of
everything around us from the movement
of tiny particles to the motion of people,
cars, and spaceships.

4. EXAMPLES OR
PRACTICAL UTILITY
Consider a smart phone, physics
describes how electricity interacts with
the various circuits inside the device.
This knowledge helps engineers select
the appropriate materials and circuit
layout when building the smart phone.

5. Consider a GPS system, physics describes
the relationship between the speed of an
object, the distance over which it travels
and the time it take to travel the distance.
When we use a GPS device in a vehicle it
utilizes the physics equation to determine
the travel time from one location to
another.

6. SUMMARY
• The study of physics is capable of
making significant contributions
through advances in new
technologies that arise from
theoretical breakthroughs.
• Physics is the foundation of many
disciplines and contributes directly
to astronomy, engineering and most
scientific fields.
