Quick answer: To learn physics efficiently, master the basic laws first, draw a diagram for every problem, understand derivations instead of memorising them, visualise what is happening, strengthen your maths, relate each concept to everyday life, and practise problems regularly. Understanding a few core ideas deeply is faster than memorising many formulas.
Physics is one of the most practical subjects you can study. It deals with nature and its phenomena: matter, energy, motion, forces and how they interact. It is full of theories, laws and relationships, and students who connect these ideas to the real world usually start to enjoy the subject and learn it more effectively.
Best tips to learn physics
The tips below will help you enjoy physics and learn it more efficiently, whether you are in school or preparing for an entrance exam.
1. Give importance to the basics
Physics builds on itself. A few fundamental ideas support many later topics, so make sure you truly understand them before moving on. For example:
- Newton’s laws of motion underpin almost all of mechanics, from friction and circular motion to rockets.
- Ohm’s law (V = IR: the current through a conductor is proportional to the voltage across it, at constant temperature) is the starting point for circuits.
- Faraday’s law of electromagnetic induction (a changing magnetic flux through a circuit induces an electromotive force) explains generators, transformers and induction cooktops.
Many other concepts revolve around these laws, so time spent on them is never wasted.
2. Draw diagrams
Drawing a diagram simplifies most problems. In mechanics, a free-body diagram showing every force on an object often makes the solution obvious. For electricity questions, always draw the circuit. In optics, draw the ray diagram. A clear diagram also helps examiners follow your answer.
3. Understand derivations
Understand derivations rather than memorising them. When you know where a formula comes from, you know when it applies, when it does not and how to rebuild it if you forget it in an exam. That understanding also makes higher-level topics easier.
4. Visualise
Picture what is happening: the field lines around a magnet, a wave travelling along a string, a ball’s path under gravity. Topics such as electric motors, electromagnetic radiation, waves and Newton’s laws make far more sense when visualised, and visualising also improves memory. Free interactive simulations, such as the PhET simulations from the University of Colorado Boulder (phet.colorado.edu), let you change variables and watch the result.
5. Develop your maths skills
Many physics topics are mathematical. Algebra, trigonometry, vectors and, at higher levels, calculus are essential for solving problems quickly and accurately. If physics problems feel hard, the gap is often in the maths; our article on the maths skills you need explains why these foundations matter.
6. Relate concepts to real life
Physics is everywhere: why a cricket ball swings, how a pressure cooker works, why the sky is blue, how a phone charger converts current. Relating concepts to things you see makes them easier to understand, raises your interest and helps you remember them.
7. Practise problems regularly
Reading alone will not make you good at physics. Solve problems every week, starting with textbook exercises and moving to harder ones. When you get one wrong, find exactly where your reasoning failed. Check units and dimensions at the end of every answer; a wrong unit often reveals a wrong method.
8. Use videos and experiments wisely
Short explanatory videos can make a topic click. BYJU’S, for example, has a five-minute video, “Understand Electricity in just 5 minutes”, embedded below. Use videos to understand, then close them and solve problems yourself. Where you can, do simple experiments at home or in the school lab.
Putting it together
Physics, properly understood, is one of the most interesting subjects there is. Keep asking why things happen and which law or theory governs them.

Frequently asked questions
What is the best way to start learning physics?
Start with the basics of motion and forces, using your school textbook, and make sure you can explain each idea in your own words and solve the exercises before moving on.
Should I memorise physics formulas?
Learn the important formulas, but understand where they come from and when they apply. Understanding lets you rebuild a formula and avoid using it in the wrong situation.
How much maths do I need for physics?
For school physics, algebra, trigonometry and basic geometry are essential, with vectors and simple calculus at senior secondary level. Higher physics needs more calculus.
Why do I understand the theory but still get problems wrong?
Usually because of too little practice, skipped diagrams or maths errors. Draw the diagram, write the knowns and unknowns, and check units at the end.
