In Physics, formulas related to mechanics, electrostatics, thermodynamics, and Modern Physics are repeatedly asked. In Chemistry, formulas from physical chemistry, such as the mole concept, thermodynamics, equilibrium, and electrochemistry, play a major role. Learning these formulas in a structured way increases confidence and reduces mistakes. Thus, mastering NEET Physics and Chemistry formulas is an important step in NEET exam preparation.

Important Physics Formula For NEET 2026 - Series LCR Circuit
Let i be the amount of current in the circuit at any time, and VL, VC, and VR the potential drops across L, C, and R, respectively.
$v_R = iR \Rightarrow$ Voltage is in phase with $i$,
$v_L = i \omega L \Rightarrow$ Voltage leads $i$ by $90^{\circ}$,
$v_C = i \omega C \Rightarrow$ Voltage lags $i$ by $90^{\circ}$.
By all these, we can draw a phasor diagram as shown below –
So, from the above phasor diagram, V will represent the resultant of vectors VR and (VL−VC).
So the equation becomes –
$V = \sqrt{V_R^2 + (V_L - V_C)^2} = \sqrt{(iR)^2 + (X_L - X_C)^2} = \sqrt{(iR)^2 + \left( \omega L - \frac{1}{\omega C} \right)^2} = iZ,$
where $Z = \sqrt{R^2 + \left( \omega L - \frac{1}{\omega C} \right)^2}$ is called the impedance of the circuit.
Also, $\tan \phi = \frac{V_L - V_C}{V_R} = \frac{X_L - X_C}{R} = \frac{\omega L - \frac{1}{\omega C}}{R}.$

Important Formulas For NEET Physics - Equations Of Motion of SHM
As we know, $a = -\omega^2 x$
General equation of SHM
1. For Displacement:
$x = A \sin(\omega t + \phi)$ ; where $\phi$ is the initial phase and $(\omega t + \phi)$ is called the phase.
Various displacement equations:
(1) $x = A \sin \omega t \Rightarrow$ when the particle starts from mean position towards right.
(2) $x = -A \sin \omega t \Rightarrow$ when the particle starts from mean position towards left.
(3) $x = A \cos \omega t \Rightarrow$ when the particle starts from extreme position towards left.
(4) $x = -A \cos \omega t \Rightarrow$ when the particle starts from left extreme position towards right.
2. For Velocity ($v$):
$x = A \sin(\omega t + \phi) \Rightarrow v = \frac{dx}{dt} = A \omega \cos(\omega t + \phi) = A \omega \sin\left(\omega t + \phi + \frac{\pi}{2}\right)$
3. For Acceleration ($a$):
$x = A \sin(\omega t + \phi) \Rightarrow v = \frac{dx}{dt} = A \omega \cos(\omega t + \phi) = A \omega \sin\left(\omega t + \phi + \frac{\pi}{2}\right)$
$\Rightarrow a = \frac{dv}{dt} = -A \omega^2 \sin(\omega t + \phi) = A \omega^2 \sin\left(\omega t + \phi + \pi\right) = -\omega^2 x$
So, the phase difference between $x$ and $v$ is $\frac{\pi}{2}$.
Similarly, the phase difference between $v$ and $a$ is $\frac{\pi}{2}$.
And, the phase difference between $a$ and $x$ is $\pi$.
Differential equation of SHM:
$\frac{dv}{dt} = -\omega^2 x \Rightarrow \frac{d}{dt}\left(\frac{dx}{dt}\right) = -\omega^2 x \Rightarrow \frac{d^2x}{dt^2} + \omega^2 x = 0$
If the motion of any particle satisfies this equation, then that particle performs Simple Harmonic Motion (SHM).

Important Chemistry NEET Formula 2026: Shapes of Molecules
The ideal shapes of molecules, which are predicted based on electron pairs and lone pairs of electrons, are mentioned in the table below:
Important formulas from Solubility and Solubility Products for NEET 2026
General Representation:
$A_xB_y \rightleftharpoons xA^{+} + yB^{-}$
$K_{sp} = [A^{+}]^x [B^{-}]^y$
Relation between Solubility ($s$) and Solubility Product ($K_{sp}$):
$A_xB_y \rightleftharpoons xA^{+} + yB^{-}$
If solubility is $s$, then $[A^{+}] = x s$ and $[B^{-}] = y s$
Thus,
$K_{sp} = (x s)^x (y s)^y = x^x y^y s^{x + y}$
The Gas Laws — Boyle’s Law (Pressure–Volume Relationship):
$P \propto \frac{1}{V} \Rightarrow PV = k \; (\text{at constant } T)$
