Physics could rich our life in certain way
First of all, Physics is a subject of natural science .It mainly
focuses on the study of substances , energy , space , time , and especially the relationship between
them .
How does Physics rich our life in certain way ? In personal point of view , One of the most
advanced and important way to rich people’s life is to invent things and inspire people into richer
way by the things that which is been invented . For instance , The Airplane. Before the Air plane was
first invented . Some of people were dreaming about fling in the air , and rest of them were laughing
at people with this kind of crazy thoughts . Certainly Mr wright built the first air machine that could
actually fly . It is associated with some of the Physics principles - The bottom of airplane wings is
designed to be more smooth , but on the top side of the wings are designed to be more curved . The
reason for that is When the air is passing by the wings. The travel distance on the top side is longer
than the bottom side because of the curved design , therefore the air speed on the top is faster than the
air speed on the bottom .when the air goes faster ,The pressure on the top side is going to be way
smaller than on the bottom side . Thus the airplane is pushed up - These Physics principles once
helped people achieving their dream , and people who do not believe them got inspired , and got the
new thought .
Physics is more like a tool . A tool to help people achieve the ideas , A tool to help people to invent ,
and certainly a tool to help people to inspire the rest of us .
