Physics

Senior Secondary School (SS1-SS3)
Summary

If you want to understand nature and how it works, you have to understand Physics.

Physics is at the very foundation of matter and energy. For example, cell phones and computers were created by following the laws of Physics that study “electricity”; Motor cars were invented when scientists discovered how to convert fuel to kinetic energy to get the car moving. Even in medical care, machines like X-rays and Ultrasounds were created by studying the principles of light and electricity.

Physics impacts our daily lives. In fact, if you look at any human invention, you will see the influence of Physics. What we discover by studying Physics, is how exactly the universe behaves.

Have you ever wondered why airplanes fly? why we don’t float up to the sky? why the sky is blue? why as humans, we walk freely without falling? why days are bright and nights are dark?. The answer to these questions and many more things you may be curious about is “Physics”.

Physics is the science that deals with the study of nature. It is about examining how matter moves through space and time and how it is affected by things like energy and force. By studying Physics, we can begin to understand the fundamental laws of nature.

Physics covers a range of topics including light, motion, electricity, force, and energy and the study of Physics has led to all kinds of inventions we use in our daily lives.

Indeed, Physics is awesome.
