Physics is such a subject that makes one think and fantasize about things that we see and use every day. This subject requires a lot of imagination and the concepts need explanation in simple language. During examinations, it becomes quite hard to understand the concepts if they are not studied daily. The main advantage of this subject is that there are certain concepts that have fixed definitions and values like the gravitational constant ‘g’ which has a fixed value. Other examples where the definition remains the same are bulk modulus, viscosity, thermodynamics laws etc.
In order to understand certain topics of Physics, one must master their basics, which can be achieved by creating a timeline for the subject or through strategies. Following are a few strategies that can be applied while preparing for the exams:
- Master the basics: This can be done by studying the subject every day and also involves the understanding of mathematics concepts like differentiation, integration etc in the derivations. Learning the units like the unit of specific resistance is ohm-meter, dimensional formula of inductance is [L]=MT-2L2A-2, memorizing basic constants like the speed of light is 3*108 ms-1 and equations like the equation of work is given as the product of displacement and force is also a part of this tip.
- Referring to previous year questions papers: This is one of the most useful tips that can be used for all subjects. Getting familiar with the question pattern gives a clear picture of chapters and topics that need to be practiced for the exam. Also, the scoring section in any exam is one mark questions, which could sometimes be problematic if the basics are not clear.
- Practicing the way of presentation of answers in the answer book: Presentation is important not just to make the answer book look neat but also makes it easy to memorize the concepts, like for Helmholtz free energy, first the definition should be written, then the mathematical representation with its units.
- Most important is understanding the concept during the lecture. Getting the doubts cleared in the classroom itself and not carrying it to self-study. Making of notes with bullet points, tables and diagrams if applicable makes it easy to understand one’s own notes.
These were few ways to study Physics which can be applied even to other subjects with required modifications. To learn more on other topics with examples, applications and with the simple explanation, visit BYJU’S.
