This introduction to physics is for anyone with a desire to learn some important basic concepts in physics. Just like mathematics, it is hard to separate physics from the world we are living in. I have created this unit so you can see how to use math to solve problems in physics.
Everything started with the study of natural philosophy. Natural philosophy used to be the study of unanswered questions about nature. As more and more answers are found, natural philosophy became science.
The physical sciences deal with nonliving things and branch into areas such as physics, geology, astronomy, and chemistry.
We will of course study physics here and introduce the most important topics to include
Mechanics : linear motion, Newton's laws, circular motion, etc.
Properties of matter : liquid , solid, or gas
Electricity and magnetism : electric current, circuits, tec.
What you get on my site is an introduction. You will not be ready to put together a rocket. However, I will help you understand all the subtleties that will prepare you for more challenging courses in physics.
No serious study can be done without a good understanding of mathematics.
We will not try to cloud physics with math, but math will help understand physics.
1. Identify a problem
2. Make an educated guess about the answer. This is called hypothesis.
3. Perform experiments to test your hypothesis
4. Formulate a general rule
When the last step in the scientific method is tested over and over again and it is still not contracted, it is then known as a law or principle.
Sometimes, scientists find new evidence that contradicts a law or principle. In this case, the previously accepted lay or principle must be rejected until another one is found.
The introduction to physics you get in this site will explain laws and principles that are accepted as of today.
Physics is a progressive science as scientists change their mind all the time, so don't be shock when a change is made. it is a good thing when they change their minds and find a better solution to explain our physical world.
