Important NEET Formulas for Physics and Chemistry are helpful for scoring well in the exam. NEET is a highly competitive test where speed and accuracy matter the most. Having all key formulas at fingertips saves time during problem-solving. The NEET formula also helps in quick revisions before the exam. A strong understanding of formulas ensures that students can focus more on applying concepts rather than recalling them.
The National Testing Agency (NTA) has activated the NEET UG 2026 application form link on the official website. Students can register themselves at neet.nta.nic.in.

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.

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, $\tan \phi = \frac{V_L - V_C}{V_R} = \frac{X_L - X_C}{R} = \frac{\omega L - \frac{1}{\omega C}}{R}.$

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).

The ideal shapes of molecules, which are predicted based on electron pairs and lone pairs of electrons, are mentioned in the table below:

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):
$P \propto \frac{1}{V} \Rightarrow PV = k \; (\text{at constant } T)$
