Important NEET 2026 Physics Formulas for Quick Revision

The following formulas are arranged systematically to help candidates prepare the NEET Physics syllabus for NEET 2026 in an organised manner:

Kinematics Formulas

Displacement: $s = ut + \frac{1}{2}at^2$

Final velocity: $v = u + at$

Velocity–displacement relation: $v^2 = u^2 + 2as$

Average velocity: $v_{\text{avg}} = \frac{u + v}{2}$

Where:
u = initial velocity
v = final velocity
a = acceleration
t = time
s = displacement

Memory tip:
Start with v=u+at. Displacement grows as ut plus the extra part from acceleration.

Projectile Motion formulas

Time of flight: $T = \frac{2u\sin\theta}{g}$

Maximum height: $H = \frac{u^2\sin^2\theta}{2g}$

Horizontal range: $R = \frac{u^2\sin 2\theta}{g}$

Where:
u = initial speed
θ = angle of projection
g = acceleration due to gravity

Work, Power, and Energy Formulas

Time of flight: $T = \frac{2u\sin\theta}{g}$

Maximum height: $H = \frac{u^2\sin^2\theta}{2g}$

Horizontal range: $R = \frac{u^2\sin 2\theta}{g}$

Heat and Temperature

Heat gained or lost: $Q = mc\Delta T$

Heat during phase change: $Q = mL$

Photoelectric Effect

Energy of photon: $E = h\nu$

Kinetic energy of emitted electron: $KE = h\nu - \phi$

Circular Motion

Centripetal force: $F = \frac{mv^2}{r}$

Angular velocity: $\omega = \frac{v}{r}$

Time period: $T = \frac{2\pi r}{v}$

Series LCR Circuit

Voltage across resistor: $V_R = iR$

Voltage across inductor: $V_L = i\omega L$

Voltage across capacitor: $V_C = \frac{i}{\omega C}$

Impedance: $Z = \sqrt{R^2 + \left(\omega L - \frac{1}{\omega C}\right)^2}$

Phase angle: $\tan\phi = \frac{\omega L - \frac{1}{\omega C}}{R}$

Simple Harmonic Motion (SHM)

Acceleration: $a = -\omega^2 x$

Displacement: $x = A\sin(\omega t + \phi)$

Velocity: $v = A\omega\cos(\omega t + \phi)$

Differential equation: $\frac{d^2x}{dt^2} + \omega^2 x = 0$

Electric Potential of Spherical Charge Distributions

Conducting sphere (outside): $V = \frac{Q}{4\pi\varepsilon_0 r}$

Conducting sphere (inside): $V = \frac{Q}{4\pi\varepsilon_0 R}$

Non-conducting sphere (inside): $V = \frac{Q}{8\pi\varepsilon_0 R^3}\left(3R^2 - r^2\right)$

Resistance and Resistivity

Resistance: $R = \rho \frac{l}{A}$

Resistivity: $\rho = \frac{m}{ne^2\tau}$

Kirchhoff's Voltage Law: $\sum V = 0$

Electromagnetic Waves

Speed of light: $c = \frac{1}{\sqrt{\mu_0\varepsilon_0}}$

Relation between fields: $B = \frac{E}{c}$

Total Internal Reflection

Critical angle: $\sin C = \frac{n_2}{n_1}$

Young's Double Slit Experiment

Bright fringe: $x = \frac{n\lambda D}{d}$

Dark fringe: $x = \frac{(2n-1)\lambda D}{2d}$

Fringe width: $\beta = \frac{\lambda D}{d}$

De Broglie Wavelength

$\lambda = \frac{h}{p}$

For electron accelerated through potential $V$: $\lambda = \frac{12.27}{\sqrt{V}}$

Logic Gates

NOT gate: $Y = 1 - A$

AND gate: $Y = A \cdot B$

OR gate: $Y = A + B$

NAND gate: $Y = 1 - A \cdot B$

NOR gate: $Y = 1 - (A + B)$
