How to learn physics from beginning?

advice to freshmen and high school physics students

 To learn physics from beginning you should first know that physics is understanding the laws of nature through math. Since you are asking this question, I’m assuming that you’re comfortable with math and science.

Are you interested in learning how electrons spin, or how heat energy and temperature is related?

Second, what do you want to do with physics? Do you want to go into academia, doing scholarly research and publishing your findings, or work in an industry?

I’d say physics is more of an academic pursuit, compared to its offshoot of engineering which is more job-oriented, Some professors at my school did their bachelor’s and master’s degree in engineering, before doing doctoral (PhD) in Physics, engineering comes after understanding the physics.

The best part about studying Physics is that it can be considered the liberal arts of the sciences. That means you’re learning about everything, such as how gases behave, how energy is transferred, how light behaves as both a wave and particle, and etc., without getting into the nitty-gritty and specifics of more focused sciences such as chemistry.

 

It will be a good idea to learn some elementary algebra and simple solutions to inequalities, From that point you can take an introductory book that deals with Newton's laws, They are by far the easiest to comprehend from a beginner , you can go further ahead in physics by studying electromagnetism or particle physics however for that you also need to step up on your math abilities , It is certainly true that without a solid math background you cannot go as deep in understanding physics phenomena .

Physics is written in the language of math so however good you are at getting general descriptions don't skip math, Whenever you feel like you have advanced on your math and consequently physics abilities you can buy for yourself Feynam's lectures on physics which is regarded as the world's best introductory to intermediate course .

 Steps to learning physics from beginning:

How to learn physics from beginning : Important advice

So  if you want to learn physics, You will need to learn concepts first, know them well enough to relate them in straight forward language that anyone can understand, Only then proceed with the math. Always keep in mind that math is to supplement physics, not supplant it. Any teacher who throws a bunch of equations, formulas, theorems and proofs at you without in any way explaining the underlying concepts is worthless, You’ll be better off studying physics  on your own <<< 👈👈

Once you  ask and get answers to these questions:

1-     What does the term (all physics happens at the margin) mean? This was bandied about when I was an undergrad, but neither one professor nor textbook ever gave an answer. If it is the underlying principle of physics, hell, of all science, then why isn’t it far better understood or explained? That should give you an insight as to the poor quality of most science I’ll give you the answer, it means that NO physics takes place until there is a change in energy, Think of the two forms of energy, potential and kinetic. What does potential mean? It means a latent ability to do something. Until it does that something, meaning transform into kinetic energy, the margin is the point where that change takes place.

2-     Why was calculus invented? Why do we take limits of a function?

3-     Understand the concept of the pure number, If you’re thinking you haven’t heard of such a thing, A pure number is a fraction, percentage, ratio, degree of an angle, slope of a line, exponent, logarithm, derivative, integral, thermodynamic entropy, on and on, By that inventory alone, it’s importance is apparent, Specifically a pure number is one that has no units, no dimensions, it isn’t a quantity of any one thing. Instead it’s a comparison, and as we learned in the first grade, you compare likes to likes. For instance, in thermo entropy, you compare heat to temperature, the SI units cancel, and guess what, you’re left with only the numbers. Why is there a distinction between heat and temperature? What is the difference between length and displacement, velocity and speed? Can’t tell you how much aggravation you will avoid if you understand those differences and why they were created. Buttonhole your proof and don’t allow them to wiggle out of not explaining those terms and differences. Forget textbooks, they’re for the most part excrementally horrible at explaining any of those terms, and more.

4-     Know the definition of a force and know its equation, Know why it works with energy change.

You’ll go a long way to understanding the conceptual underpinning of physics if you answer those questions, you’ll find that conceptually, physics and the sciences aren’t difficult to understand, that people of normal intelligence can readily enjoy and apply physics to their lives. Don’t allow teachers to bury their lectures with math, you’ll get very little out of your study if you think that is a proper teaching method.

 

5-     Applications of physics are easy to learn and enjoy as you would read a magazine on technology and  renewable energy, an electric motor powering a bike, use of a pump to remove water from a pond,
However to enjoy physics at and beyond secondary school level would require you mastering the basics in Math’s.

 

6-     Many say Physics and Math’s are sister sciences many Physics students at the university take a lot of Math’s courses, including Calculus courses.
Mastering the basics in Math means reviewing addition, subtraction, multiplication and division operations and others, as well as reviewing concepts in Algebra and use of formulas, with related graphs. (You must be at home in dealing with numbers, almost all Physics courses would require your knowledge to deal with mathematical operations and related concepts as in the use of equations.)


 Take concepts in Relativity; you will appreciate that better if you are sure of working with the basic (speed = distance/time) formula.
It does not matter how complicated a formula may look in a lesson, if you can see what basic formula it is built on, you will better understand the concepts taught.

7-     While reviewing Math’s read Science and Physics magazines where a lot of applications(machines, tools, devices)are described ,That should help you appreciate the principles of Physics and Math’s or Engineering.

  applied in everyday life, Hopefully that should urge you to get excited about the subject too ,Lastly, read the lives of great Physicists and see how they used their knowledge and skills to contribute to making the world what it is today – read the lives of Isaac Newton, Albert Einstein, Marie and Pierre Curie, Irene Joliot-Curie, Lise Meitner, Blaise Pascal, Archimedes, Galileo etc.

 

Learn Physics by app on the Google Play:

Great physics resource is the Ideal Physics app on the Google Play Store. It contains notes, equations, and practice problems with step by step solutions on all of the major areas of physics, the topics it covers are Astrophysics, Electricity & Magnetism, Mechanics, Modern Physics, Optics & Waves, Quantum Mechanics, and Thermodynamics, There are also some useful tools included like physical constants, a unit converter, and some mathematics review. The math level ranges from algebra to calculus so are prepared for that, There is a free version of the app, but it does not include the practice problems that are really helpful. I highly recommend this for university freshmen and high school physics students << 👈👈.
