Physics can be a difficult course to take in school and many people struggle to get a grasp on some of the basic concepts. While some people find physics fairly easy to comprehend, others may constantly get bad grades in physics and never seem to be able to keep up with the lessons. If you have been having a hard time with your physics lessons, then take a moment to go over these tips for learning how to gain a better understanding of physics.
Memorizing the Basic Constants and Equations
Throughout your physics lessons, you will notice that there are many basic constants and equations that are repeated throughout the course. Certain facts are considered constants, such as the force of gravity on earth. The way that different forces interact is typically represented in the form of an equation. To begin getting a better grasp on physics, take the time to memorize the most used basic constants and basic equations. This will take care of half the difficulty in overcoming the majority of physics questions. Even if you come across a complex physics question, understanding these equations and constants will give you the base understanding of the problem, so that you at least have an idea of what each question is asking.
To go along with this, you should also start learning the derivation of basic equations. This means that you should take time to understand why the basic equations that you learnt work the way they do. You will gain a clearer picture of how physics works as well as how equations can be used to solve physics problems.
Acquire the Necessary Math Skills
There is a lot of math used in physics. For example, the equations that you took the time to learn use various principles found in math. In order to become good at physics, you need to be good at math. For starters, you will need understand algebra in order to follow the use of basic physics equations. In many school systems, algebra is a prerequisite to learning physics. Trigonometry is useful for understanding force diagrams and rotation problems. Geometry is commonly used for determining the answer to problems involving volume, area, and other geometrical formulas. Finally, calculus is needed for more advanced physics lessons. If you are taking an introductory physics course, you should be fine with an understanding of algebra and geometry. The other math skills will become useful as you start studying more advanced physics.
Solving Physics Problems
The tips above will help you with your overall understanding of physics. When it comes time to put those skills to the test, it will help if you know how to attack a physics a problem. Start by focusing on the most important information in the problem. Read the entire problem and identify which parts are important and which physics equations you will need to solve the problem. You should also make sure that you use the correct units when solving a problem. Forgetting to label units could lead to mistakes when calculating an equation. Once you have gone through the problem, identify the necessary information needed to solve the problem, and listed your equations, you can start solving the actual problem. Write everything out, as even the more basic physics problems can involve multiple math calculations. Even a single error can result in the entire answer being wrong. Always double check every part of your answer, especially the math formulas and calculations. Finally, take your time when answering a question. Stay calm and read the problem thoroughly before you even begin to write down equations and start your calculations.
Physics does not have to be an extremely challenging subject. Keep a level head and learn the basics. Start with the memorization of constants and equations and then ensure you have the proper math skills. Always ask your instructor or teacher questions if you are struggling with any part of the lesson. If you follow these tips, you will be on your way to getting a perfect grade in physics in no time.
