Class 11 Physics High-Yield Formulas

1. Kinematics & Motion in a Straight Line / Plane

Kinematics forms the foundation of mechanics. Focus on vectors and standard equations of motion under uniform acceleration.

• Equations of Motion (Constant Acceleration): [v = u + at] [s = ut + \frac{1}{2}at^2] [v^2 = u^2 + 2as]

• Projectile Motion Parameters:

  • Time of Flight: [T = \frac{2u \sin\theta}{g}]
  • Maximum Height: [H = \frac{u^2 \sin^2\theta}{2g}]
  • Horizontal Range: [R = \frac{u^2 \sin(2\theta)}{g}]
  • Trajectory Equation: [y = x \tan\theta - \frac{g x^2}{2u^2 \cos^2\theta}]

2. Work, Energy, and Power

• Work Done by Variable Force: [W = \int F \cdot dx]

• Work-Energy Theorem: [W_{\text{net}} = \Delta K = K_f - K_i]

• Potential Energy of a Spring: [U = \frac{1}{2}kx^2]

• Instantaneous Power: [P = \vec{F} \cdot \vec{v} = Fv \cos\theta]

3. Gravitation

• Universal Law of Gravitation: [F = \frac{G m_1 m_2}{r^2}]

• Variation of Acceleration due to Gravity (g):

  • At height (h) above Earth surface: [g' = g\bigl(1 - \frac{2h}{R}\bigr)]
  • At depth (d) below Earth surface: [g' = g\bigl(1 - \frac{d}{R}\bigr)]

• Escape & Orbital Velocity:

  • Escape Velocity: [v_e = \sqrt{\frac{2GM}{R}} = \sqrt{2gR}]
  • Orbital Velocity: [v_o = \sqrt{\frac{GM}{R}}]

4. Thermodynamics & Kinetic Theory of Gases (KTG)

• First Law of Thermodynamics: [\Delta Q = \Delta U + W]

• Molar Specific Heat Relation: [C_p - C_v = R]

• Ideal Gas Law & RMS Speed: [PV = nRT] [v_{\text{rms}} = \sqrt{\frac{3RT}{M}}]

Class 12 Physics High-Yield Formulas

5. Electrostatics & Current Electricity

• Coulomb's Law: [F = \frac{1}{4\pi \varepsilon_0} \frac{q_1 q_2}{r^2}]

• Electric Field due to Point Charge: [E = \frac{1}{4\pi \varepsilon_0} \frac{q}{r^2}]

• Ohm's Law & Resistance: [V = IR] [R = \frac{\varrho l}{A}]

• Electrical Power Dissipation: [P = VI = I^2 R = \frac{V^2}{R}]

6. Ray Optics & Wave Optics

• Mirror Formula: [\frac{1}{f} = \frac{1}{v} + \frac{1}{u}]

• Lens Maker's Formula: [\frac{1}{f} = (n - 1)\Biggl(\frac{1}{R_1} - \frac{1}{R_2}\Biggr)]

• Young's Double-Slit Experiment (Fringe Width): [\beta = \frac{\lambda D}{d}]

7. Modern Physics (Photoelectric Effect, Atoms & Nuclei)

Modern Physics is one of the highest return-on-investment (ROI) units in NEET, offering direct application of fundamental equations.

• Einstein's Photoelectric Equation: [E = h\nu = W_0 + K_{\text{max}}] [K_{\text{max}} = eV_0]

• de Broglie Wavelength: [\lambda = \frac{h}{p} = \frac{h}{mv} = \frac{h}{\sqrt{2mK}}]

• Bohr Radius & Energy Levels in Hydrogen Atom: [r_n = 0.529 \times n^2 \text{ \AA}] [E_n = -\frac{13.6}{n^2} \text{ eV}]

How to Effectively Use This Formula Sheet for NEET 2027

1. Build a Personal Formula Diary: Do not just rely on digital PDFs. Handwrite every equation in a designated short-notes notebook. The physical process of writing reinforces neural pathways for memory retention.
2. Master Variable Definitions & Units: Knowing the formula is only half the battle. Always write down what each variable represents and its standard SI unit (e.g., in (P = I^2 R), current (I) is in Amperes and resistance (R) is in Ohms).
3. Practice Active Recall Daily: Dedicate 15 minutes every morning to active formula recall. Pick 5 random chapters, close your notes, and write down all formulas you remember from memory.
4. Apply Formulas to Previous Year Questions (PYQs): Immediately solve at least 15–20 NEET PYQs after revising a formula block. Pay attention to how questions twist variables or require combining two formulas from different chapters.
