NEET 2023 Important Formulas of Physics

In NEET 2023 preparation for the exam, a chart of Important Formulas of Physics will be very helpful to all NEET aspirants. Every time it’s very difficult to remember all the Physics formulas from different chapters. So topic-wise important formulas of Physics for NEET 2023 are listed below:

Important Formulas

• Gravitation constant G = 6.67×10⁻¹¹ N m²/kg² ​​
• Planck constant h = 6.63 × 10⁻³⁴s = 4.136 × 10^-15 eV.s
• Boltzmann constant k = 1.38 × 10⁻²³ J/K
• Avogadro’s number NA = 6.023 × 10²³ mol⁻¹
• Molar gas constant R = 8.314 J/(mol K)
• Charge of electron e = 1.602 × 10⁻¹⁹ C
• Coulomb constant 1/4πε0 = 8.9875517923(14) × 10⁹ N m²/C²
• Permittivity of vacuum 0 = 8.85 × 10⁻¹² F/m
• Faraday constant F = 96485 C/mol
• Mass of electron me = 9.1 × 10⁻³¹ kg
• Mass of proton mp = 1.6726 × 10⁻²⁷ kg
• Mass of neutron mn = 1.6749 × 10⁻²⁷ kg
• Rydberg constant R∞ = 1.097 × 10⁷ m⁻¹
• Bohr magneton µB = 9.27 × 10⁻²⁴ J/T
• Bohr radius a0 = 0.529 × 10⁻¹⁰ m
• Standard atmosphere atm = 1.01325 × 10⁵ Pa
• Wien displacement constant b = 2.9 × 10⁻³ m K.
• Wave = ∆x ∆t wave = average velocity ∆x = displacement ∆t = elapsed time.
• Stefan-Boltzmann constant σ = 5.67 × 10⁻⁸ W/(m² K⁴)
• Vavg = (vi + vf*)²

Important Symbols

• a = ∆v ∆t,

A = acceleration

∆v = change in velocity

∆t = elapsed time.

• ∆x = vi∆t + 1/2 a(∆t)²

∆x = the displacement

vi = the initial velocity

∆t = the elapsed time

a = the acceleration

Use this formula when you don’t have vf.

• ∆x = vf∆t − 1/2 a(∆t)²

∆x = displacement

vf = is the final velocity

∆t = elapsed time

a = acceleration

Use this formula when you don’t have vi.

• F = ma

F = force

m = mass

Then a = acceleration Newton’s Second Law.

F is the net force on the mass m.

• W = mg

W = weight

m = mass

g = acceleration which is due to gravity.

Then we see that the weight of an object with mass m. This is said to be really just Newton’s Second Law.

• f = µN f = friction force

µ = coefficient of friction

N = normal force

Here µ can be either the kinetic coefficient of friction µk or the static coefficient of friction.

• p = mv
• W = F d cos θ

W = work t

F = force

d = distance

θ = angle between F and the direction of motion

• KE = 1/2 mv² K

KE = kinetic energy

m = mass

v = velocity

• PE = mgh

PE = potential energy

m = mass

g = acceleration due to gravity

h = height

• W = ∆(KE)

W = work done

KE = kinetic energy.

The “work energy” that we have learned is the theorem that the work done by the net force on an object equals the change in kinetic energy of the object.

We can write it as E = KE + PE

E = total energy

KE = kinetic energy

PE = potential energy
