Preparation tips for NCERT Class 12 Physics

For some, being good at physics comes naturally; however, it takes some effort to master physics and become an expert at the subject. Luckily, by developing some foundational skills and consistently practising, almost anyone can get good at physics. In this article, we will discuss some practises that will help you get better at Physics.

Learn the Math skill required to Solve Physics Problems

Physics incorporates a lot of mathematics into it to explain physics concepts. This is why it is necessary to be proficient in mathematics to get good at Physics.

Use Flash Cards

Note formulas, new terms and equations in a flashcard! For demonstration purposes, let us consider the alternating current formula. An alternating current is a current that changes its magnitude and polarity at a regular interval of time. The concept of alternating current entails many formulae, to remember all of them effectively, it would help if you noted them down in flashcards.

Draw the concepts

Drawing concepts helps you retain them better and aids in memorization. For example, the electromagnetic waves definition states that they are waves that are created as a result of vibrations between an electric field and a magnetic field. The electromagnetic waves are composed of oscillating magnetic and electric fields. Illustrating electromagnetic waves will help you retain the definition better when you can picturise the wave.

Learning Pesky Laws and Equations

Physics is a subject rich in equations, laws and formulas. Instead of memorizing the equations, work through its derivation because memorization is a low form of learning.

Read the Upcoming Topics before Lectures

It is better not to come across any topic for the first time in class. Instead, read the upcoming topics the day before it is covered in the class. While doing so, grasp the general principles of the topic and donot fixate on the precise mathematics. This practice will help you build a solid foundation of knowledge upon which you can build the knowledge by applying mathematical skills that will be taught in the class the next day.


Constant Practice

Do not wait until the exam to start practising or revising concepts discussed in the class. Physics requires you to constantly practise and put in consistent effort to get good at the subject, after all world class physicists did not master various laws of physics overnight, did they?

Using Correct Units

Forgetting to label the answers with incorrect units can cost a lot of marks in exams. Below are a few commonly used parameters and their units:

  • Force – Newtons
  • Mass – grams or kilograms
  • Energy – Joules
  • Unit of Inductance – Henry
  • Acceleration – meters/seconds2
  • Unit Capacitance – Farad

These were some tips that will definitely help you score well in the exam. The secret is to study throughout the year without having put much effort at the last minute. All the Best!
