Success in NEET depends not only on conceptual understanding but also on the ability to recall formulas accurately under exam pressure. Physics questions often require direct application of formulas from Mechanics, Current Electricity, Modern Physics, Oscillations, and Optics. Similarly, Chemistry includes formula-based questions from Mole Concept, Equilibrium, Thermodynamics, Electrochemistry, Solutions, and States of Matter. A well-organised NEET 2026 Formula Sheet can significantly reduce revision time and improve accuracy.
This article provides the most important Physics and Chemistry formulas for Re NEET 2026, along with chapter-wise formula PDFs, high-scoring concepts, and quick revision resources. Aspirants can use these formula sheets during the final months of preparation to strengthen concepts and maximise their NEET exam score.

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.
vR=iR⇒ Voltage is in phase with i,
vL=iωL⇒ Voltage leads i by 90∘,
vC=iωC⇒ Voltage lags i by 90∘.
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=VR2+(VL−VC)2=(iR)2+(XL−XC)2=(iR)2+(ωL−1ωC)2=iZ,
where Z=R2+(ωL−1ωC)2 is called the impedance of the circuit.
Also, tanϕ=VL−VCVR=XL−XCR=ωL−1ωCR.

As we know, a=−ω2x
General equation of SHM
1. For Displacement:
x=Asin(ωt+ϕ) ; where ϕ is the initial phase and (ωt+ϕ) is called the phase.
Various displacement equations:
(1) x=Asinωt⇒ when the particle starts from mean position towards right.
(2) x=−Asinωt⇒ when the particle starts from mean position towards left.
(3) x=Acosωt⇒ when the particle starts from extreme position towards left.
(4) x=−Acosωt⇒ when the particle starts from left extreme position towards right.
2. For Velocity (v):
x=Asin(ωt+ϕ)⇒v=dxdt=Aωcos(ωt+ϕ)=Aωsin(ωt+ϕ+π2)
3. For Acceleration (a):
x=Asin(ωt+ϕ)⇒v=dxdt=Aωcos(ωt+ϕ)=Aωsin(ωt+ϕ+π2)
⇒a=dvdt=−Aω2sin(ωt+ϕ)=Aω2sin(ωt+ϕ+π)=−ω2x
So, the phase difference between x and v is π2.
Similarly, the phase difference between v and a is π2.
And, the phase difference between a and x is π.
Differential equation of SHM:
dvdt=−ω2x⇒ddt(dxdt)=−ω2x⇒d2xdt2+ω2x=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:
AxBy⇌xA++yB−
Ksp=[A+]x[B−]y
Relation between Solubility (s) and Solubility Product (Ksp):
AxBy⇌xA++yB−
If solubility is s, then [A+]=xs and [B−]=ys
Thus,
Ksp=(xs)x(ys)y=xxyysx+y
The Gas Laws — Boyle’s Law (Pressure–Volume Relationship):
P∝1V⇒PV=k(at constant T)
Frequently Asked Questions (FAQs)
A NEET formula sheet helps candidates revise important Physics and Chemistry formulas quickly before the exam. It also saves time during revision and improves problem-solving speed.
Yes, these formulas will be helpful for the Re-NEET 2026 exam as well. Since Re-NEET 2026 follows the same NEET syllabus and exam pattern, the important Physics and Chemistry formulas remain relevant for preparation, revision, and practice.
Students should use the NEET formula sheet for daily revision, last-minute preparation, and quick recap before mock tests. It is also helpful for identifying frequently used formulas from high-weightage chapters.
Formulas are mainly important for Physics and Chemistry in NEET, especially for numerical and application-based questions. Biology has fewer direct formulas but includes important ratios, laws, and concepts in topics such as Genetics and Ecology.
