Tips and Tricks to remember physics formula sheet
There are several tricks you can use to remember physics formulas. Here are some suggestions:
Practice, practice, practice: The more you use the formulas, the easier they will be to remember. Practice applying the formulas to different problems and situations.
Group related formulas together: Try to group related formulas together based on the type of problem they are used for, such as kinematics, dynamics, or energy. This will help you remember them better and make it easier to find the right formula for a particular problem.
Use mnemonic devices: You can create mnemonic devices to help you remember formulas. For example, the formula for the circumference of a circle is C = 2πr. You can remember this by thinking "See Two Pi R" or "Cats Are Too Pretty".
Make flashcards: Write the formulas on one side of a flashcard and the definition or explanation on the other side. Review the flashcards regularly to help reinforce your memory.
Draw diagrams: Drawing diagrams and labeling them with the relevant formulas can help you remember them better. For example, if you're studying kinematics, you can draw a diagram of a moving object and label it with the relevant formulas.
Use online resources: There are many online resources available that provide formula sheets and practice problems. Use these resources to review and practice the formulas regularly.
Remember, the key to remembering physics formulas is practice and repetition. The more you use the formulas, the easier they will be to remember.

To score good marks in physics, one should consider the following
1. Understand the basic concepts: Physics is a subject that requires a clear understanding of fundamental concepts. Ensure that you have a strong foundation of the concepts before moving on to complex topics.
2. Practice regularly: Physics is a subject that requires practice. Practice numerical problems and derivations regularly to get a good grasp of the concepts.
3. Be thorough with the formulas: Memorize all the essential formulas and understand the conditions under which they are applicable. This will help you in solving problems more efficiently.
4. Use diagrams and graphs: Physics is a subject that involves a lot of diagrams and graphs. Understand and practice drawing diagrams and graphs, and learn how to analyze them to obtain relevant information.
5. Revise regularly: Physics is a subject that requires continuous revision. Revise regularly to keep the concepts fresh in your mind.
6. Solve previous years' question papers: Solving previous years' question papers will give you an idea about the exam pattern and the types of questions asked. It will also help you in time management during the actual exam.
7. Seek help when needed: If you face any difficulty in understanding any concept or solving any problem, do not hesitate to seek help from your teacher or mentor.
Remember, scoring good marks in physics is not only about memorizing the concepts and formulas but also about applying them correctly in solving problems.
