Repetition is key to remembering formulas. Solve as many times as you can. Better yet, stop trusting your formula sheet and try to solve problems by relying solely on your brain. Of course, don't forget to check if your answer is correct or wrong.
We need to remember the formula for solving numerical problems. If you don't remember, you'll make a mistake, spend more time on a question, and you might even lose few grades on the exam. Here are some useful techniques for effectively memorizing physics. Practicing the formula makes a student perfect.
As in other subjects, it is also important for physical formula, repetition is a very important aspect of learning. If you practice a new skill, the connections between brain neurons are strengthened. But if you don't practice, then weak ties break. If you try to learn formulas without doing the practice first, then you're just making it harder, so leave the formula book separate and try to solve the questions, this way your mind will try to learn the formula.
When you use things often enough, you tend to remember them. If you haven't used a particular equation for a while, you'll tend to need a reminder. Being a researcher doesn't mean you get tested by the number of equations you know. We always have access to the Internet and the library, and you are expected to search for things on a daily basis.
Keep a list of symbols Most physical formulas include some Greek letters, or perhaps some strange symbols like ^ or perhaps a letter with a slash at the top. One of the hardest things about learning mathematics and physics is keeping in mind all the formulas you need. But there are some results in physics that are impossible to memorize because they are too big. If you need to memorize mathematical and physical formulas, use a mnemonic device, in which you can make a new sentence using the first letter of the keywords or variables in the formula so that you can remember the formula more easily.
Most of my teachers have said at one time or another that they only have about 10 physics equations memorized. Usually, if you start making some effort to memorize in physics, such as making flashcards, something goes wrong.
