📜 A Little History of 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 were found, natural philosophy became science.

The study of science is divided into the study of living things (life sciences) and the study of nonliving things (physical sciences).

The life sciences deal with living things and branch into areas such as biology, botany, and zoology.

The physical sciences deal with nonliving things and branch into areas such as physics, geology, astronomy, and chemistry.

🎓 Why Do You Need These Lessons?

Are you a student in high school and you need a solid introduction to help you tackle the jargon you hear from your teacher?
Are you in college and you feel like you are falling behind? Get back on track here before it is too late.
Are you just curious about physics? You have never learned physics before and you need some good guidelines to get started without the exorbitant cost of taking a course.

🔬 The Scientific Method

Identify a problem.
Make an educated guess about the answer. This is called a hypothesis.
Perform experiments to test your hypothesis.
Formulate a general rule.

When the last step in the scientific method is tested over and over again and it is still not contradicted, 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 law or principle must be rejected until another one is found.

The physics lessons you get on this site will explain laws and principles that are accepted as of today.

Physics is a progressive science as scientists and physicists change their minds all the time, so don't be shocked 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.

❓ High School Physics FAQs

Is physics a hard class?

Well, it depends! Is learning math hard? Is learning a new language hard? Is it hard to show kindness? Is it hard to stick to a diet? I think it depends on your attitude and how motivated you are. A high school physics course is not a rocket science course, and it is not meant to challenge you beyond your ability. However, among other important things, you need to pay attention in class, open your physics book and read the material carefully, ask questions when you do not understand, and do your homework.

What do you learn in high school physics?

The physics lessons here will introduce you to the most important topics, including the following:

Mechanics: linear motion, Newton's laws, circular motion, etc.
Properties of matter: liquid, solid, or gas
Electricity and magnetism: electric current, circuits, etc.

You should also expect to go to a lab class to conduct some experiments based on the things you are learning in class.

Why is physics so hard?

No serious study of physics can be done without a good understanding of mathematics. The lessons in this unit will not try to cloud physics with math, but math will help you understand physics. Many teachers have said that they ended up teaching math in a physics class. If you find it hard to learn physics, it may be because you need to strengthen your math skills. Keep in mind that the better you understand math, the more comfortable you could be with physics.

What is the easiest concept in physics?

Linear motion is the easiest concept in physics. Linear motion usually starts with a definition of speed.

Should I take high school physics?

If you are confident in your math skills, it is not a bad idea to take high school physics. Physics will bring math to life as you explore some interesting topics. The better you understand physics, the more well-rounded you could be with other branches of science. You will not be ready to put together a rocket, not yet. However, high school physics will lay down some of the foundations in order to take more challenging courses in physics such as nuclear physics or modern physics.
