Introduction to Physics
Physics is a branch of science that studies the nature and properties of matter and energy. It
involves figuring out how things work in the world and the universe.
Why do we study physics?
Physics is present all around us and it plays an important role in our lives. Studying physics helps
us in the following:

Understand the world: It helps us understand how natural and man-made systems
work.

Development of technology: Physics contributes to the creation and improvement of
technology such as computers, smartphones, and medical devices.

Solve real-world problems: By understanding physical laws we can tackle issues like
climate change and energy conservation.

Improved decision-making: A good understanding of physics can help make better
decisions in everything from construction to space exploration.
