    However, simply memorising formulas is not enough. You need to understand how they are applied in real exam questions. 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, are important. 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

    1714040187791

    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 –

    1714040187642

    So, from the above phasor diagram, V will represent the resultant of vectors VR and (VL−VC).

    So the equation becomes –

    V=VR2+(VLVC)2=(iR)2+(XLXC)2=(iR)2+(ωL1ωC)2=iZ,

    where Z=R2+(ωL1ωC)2 is called the impedance of the circuit.

    Also, tanϕ=VLVCVR=XLXCR=ωL1ωCR.

    Important Formulas For NEET Physics - Equations Of Motion of SHM

    1714040187952

    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=ω2xddt(dxdt)=ω2xd2xdt2+ω2x=0

    If the motion of any particle satisfies this equation, then that particle performs Simple Harmonic Motion (SHM).

    Important formulas from Solubility and Solubility Products for NEET 2026

    General Representation:

    AxByxA++yB

    Ksp=[A+]x[B]y

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

    AxByxA++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):

    P1VPV=k(at constant T)
