NEET Physics Formula Sheet

We have curated the important physics formulas for NEET based on the NEET exam trends observed in the previous 5 years. The table consists of the highest-scoring concepts in the last 5 years, the number of times they appeared in NEET, and the years in which questions were based on these concepts. The physics NEET formula sheet is based on these high-scoring concepts.

Important Physics Formula For NEET - Series LCR Circuit

Let '$i$' be the amount of current in the circuit at any time, and $V_L$, $V_C$, and $V_R$ 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 is leading $i$ by $90^\circ$

$v_C = \frac{i}{\omega C} \Rightarrow$ voltage is lagging behind $i$ 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 $V_R$ and $(V_L - V_C)$. So the equation becomes –

$V = \sqrt{V_{R2} + (V_L - V_C)^2} = i \sqrt{R^2 + (X_L - X_C)^2} = i \sqrt{R^2 + (\omega L - \frac{1}{\omega C})^2} = iZ$

where,

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

Here, $Z$ is called the impedance of this circuit.

Now, come to the phase angle. The phase angle for this case is given as –

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

Important Formulas For NEET Physics - Equations Of Motions Of SHM

As we know, $a = -\omega^2 x$

\begin{itemize}

\item General equation of SHM

\end{itemize}

1. For Displacement:–

$x = A \sin(\omega t + \phi)$; where $\phi$ is initial phase and $(\omega t + \phi)$ is called the phase.

Various displacement equations:–

(1) $x = A \sin \omega t \Rightarrow$ when particle starts from mean position towards right.

(2) $x = -A \sin \omega t \Rightarrow$ when particle starts from mean position towards left.

(3) $x = A \cos \omega t \Rightarrow$ when particle starts from extreme position towards left.

(4) $x = -A \cos \omega t \Rightarrow$ when particle starts from left extreme position towards right.

2. For Velocity (v):–

$x = A \sin(\omega t + \phi) \Rightarrow v = \frac{dx}{dt} = A \omega \cos(\omega t + \phi) = A \omega \sin(\omega t + \phi + \frac{\pi}{2})$

3. For Acceleration:–

$x = A \sin(\omega t + \phi) \Rightarrow v = \frac{dx}{dt} = A \omega \cos(\omega t + \phi) = A \omega \sin(\omega t + \phi + \frac{\pi}{2}) \Rightarrow a = \frac{dv}{dt} = -A \omega^2 \sin(\omega t + \phi) = A \omega^2 \sin(\omega t + \phi + \pi) = -\omega^2 x$

So, here we can see that the phase difference between x and v is $\frac{\pi}{2}$

Similarly, the phase difference between v and a is $\frac{\pi}{2}$

Similarly, the phase difference between a and x is $\pi$

\begin{itemize}

\item Differential equation of SHM:–

\end{itemize}

$\frac{dv}{dt} = -\omega^2 x \Rightarrow \frac{d}{dt} \left( \frac{dx}{dt} \right) = -\omega^2 x \Rightarrow \frac{d^2 x}{dt^2} + \omega^2 x = 0$

If the motion of any particle satisfies this equation, then that particle will do SHM.

NEET Chemistry Formula List

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 2025

General Representation: $AxBy \rightleftharpoons xA^{+} + yB^{-}$, $K_{sp} = [A^{+}]^x [B^{-}]^y$

Relation between Solubility (s) and Solubility Product (Ksp):

$AxBy \rightleftharpoons xA^{+} + yB^{-}$

$s \rightarrow 0 \quad 0 \rightarrow xs \quad ys$

Thus, $K_{sp} = x^x y^y (s)^{x+y}$
