how to really understand physics in 2020

 how to really understand physics


1. Course Preparation: Your math skills need to be good! The majority of the problems students have with PHYSICS can be traced to MATH weakness, not to a lack of understanding of PHYSICS. Algebra and trigonometry plus some simple calculus are assumed. There will be NO TIME to review math or to teach it to you.

a. Brush up on your math skills, especially if it’s been a while since you had it.

b. Use and refer to the Math Review in the Appendices of the book.


2. Learning to Learn: Many problems in PHYSICS (and others courses) can be traced to students not knowing how to study and learn.

a. Spend more time on what you know you are weak on.

b. READ & USE THE BOOK! You’ve spent big $$ for the book. USE IT! Usually, reading the material before lecture is better. Read each chapter more than once. Work the examples in the book and work problems at the end of the chapters, even some that are NOT assigned.

c. DO THE ASSIGNED HOMEWORK!! You can’t learn physics without doing problems!

d. COME TO CLASS!! Unless you are a genius, coming to class is necessary to understand the material. Pay attention to the lecture, the DEMONSTRATIONS, and other visual aids.

e. STUDY!! Rule of thumb: Spend 2-3 hours outside of class for every hour in class. Study in a quiet place and when you are rested.

3. Working with Others: People in most professions almost always work together in groups or teams because that is an efficient way to work. Studying physics together in groups is also efficient. You are strongly encouraged to form a study group with people in the class. If you don’t have friends in the class, now is the time to make some! Work on homework problems and study for exams together.

4. Lectures and Note Taking: Taking notes in outline form might be helpful. Some faculty post lecture notes on the web. For best results, download & print out the lecture notes BEFORE lecture & take notes as you proceed.

5. Other Helpful Hints:
Ask Questions in Class!
See your instructor during office hours.
Make use of the TA Office Hours in Room 004.
Come to Problem Solving Sessions some faculty arrange & also SI Sessions.


6. Examinations: Prepare for exams by studying the material as it is covered. Avoid cramming before an exam!! Cramming may get you through the present exam, but you will not retain concepts for use on the next exam or the Final.

      Each of us has a different learning style and a preferred means of learning. Understanding your own learning style will help you to focus on aspects of physics that may give you difficulty and to use those components of your course that will help you overcome the difficulty. Obviously you will want to spend more time on those aspects that give you the most trouble. If you learn by hearing, lectures will be very important. If you learn by explaining, then working with other students will be useful to you. If solving problems is difficult for you, spend more time learning how to solve problems. Also, it is important to understand and develop good study habits. Perhaps the most important thing you can do for yourself is to set aside adequate, regularly scheduled study time in a distraction-free environment. 



Lectures and Taking Notes in physics


An important component of any college course is the lecture. In physics this is especially important because your professor will frequently do demonstrations of physical principles, run computer simulations, or show video clips. All of these are learning activities that will help you to understand the basic principles of physics. Don’t miss lectures, and if for some reason you do, ask a friend or member of your study group to provide you with notes and let you know what happened. Take your class notes in outline form, and fill in the details later. It can be very difficult to take word for word notes, so just write down key ideas. Your professor may use a diagram from the textbook. Leave a space in your notes and just add the diagram later. After class, edit your notes, filling in any gaps or omissions and noting things you need to study further. Make references to the textbook by page, equation number, or section number.
Make sure you ask questions in class, or see your professor during office hours. Remember the only “dumb” question is the one that is not asked. Your college may also have teaching assistants or peer tutors who are available to help you with difficulties you may have.
