The Road to Mastery
Physics is a journey. It starts with observing the world around you (Why do apples fall? Why does light bend?) and ends with explaining the universe through mathematics. This studio is organized to match your academic growth.

2. The Core
Class 9 - 10
The Board Exam years. Here you meet the "Equations of Motion", Newton's Laws, and Ohm's Law.
Key Topics: Gravitation, Work & Energy, Electricity.
3. Advanced
Class 11 - 12
Pre-University/College level. Vectors, Calculus, and Abstract concepts.
Key Topics: Rotational Motion, Thermodynamics, Electrostatics.
Exam Strategy: The "Cheat Sheet" Mindset
You cannot check a formula sheet during an exam, but you can build one in your head.
- Group by Units: Don't just memorize $F=ma$. Memorize that Force is in Newtons. If you forget the formula, just remember $N = kg \cdot m/s^2$. The units give you the formula!
- Visualize the Graph: For $v=u+at$, visualize a Velocity-Time graph. The slope is 'a'. The formula is just the equation of that line.
- Use the Flashcards: Switch to the "Exam Flashcards" tab and filter for your class. Test yourself daily until you can recall the formula instantly.
Frequently Asked Questions
What are the 3 Equations of Motion?
For uniformly accelerated motion: 1) v = u + at (Velocity-Time), 2) s = ut + ½at² (Position-Time), and 3) v² = u² + 2as (Position-Velocity). These are the pillars of Class 9 Kinematics.
What is the Mirror Formula for Class 10?
The Mirror Formula is 1/f = 1/v + 1/u, where 'f' is focal length, 'v' is image distance, and 'u' is object distance. Remember the sign convention: 'u' is always negative!
How is School Physics different from College Physics?
School physics (Class 6-12) focuses on 'Classical Physics'—Mechanics, Electromagnetism, and Optics—using algebra and basic calculus. College physics delves deeper into Quantum Mechanics, Relativity, and rigorous vector calculus.
What is the most import formula for Class 12 Electricity?
Ohm's Law (V=IR) is fundamental, but for Class 12, Kirchhoff's Laws (KCL and KVL) and the Potentiometer principle are crucial for solving complex circuit diagrams.
How can I memorize these formulas effectively?
Don't just rote learn! Use our 'Exam Flashcards' tab. Also, try deriving them. If you know that F=ma, you can derive the momentum formula. Understanding the 'why' makes the 'what' stickier.
Why is 'g' taken as 9.8 or 10?
The acceleration due to gravity on Earth is exactly ~9.81 m/s². However, in many school exams (especially Class 9 & 10), questions will ask you to use g = 10 m/s² to simplify calculations.
Do I need Calculus for Class 11 Physics?
Yes! Class 11 introduces Instantaneous Velocity (v = dx/dt) and Work done by variable force (W = ∫F.dx). Basic differentiation and integration are essential tools.
