NEET Physics Important Formulas

Candidates need to prepare all the physics formulas for NEET for the accurate application of principles and physics concepts. So, to gauge a topic better, one has to be aware of all the Physics formulas for NEET. Here are some crucial Physics formulas for NEET 2025 that one must refer to:

• Boltzmann constant, k = 1.38 × 10 ⁻²³ J/K

• Gravitation constant, G = 6.67×10 ⁻¹¹ m ³ kg ⁻¹ s ⁻²

• Planck constant, h = 6.63 × 10 ⁻³⁴ J.s = 4.136 × 10 ^-15 eV.s

• a = ∆v ∆t, where A = acceleration, ∆v = change in velocity and ∆t = elapsed time.

• Charge of electron, e = 1.602 × 10 ⁻¹⁹ C

• Avogadro’s number, NA = 6.023 × 10 ²³ mol ⁻¹

• Molar gas constant, R = 8.314 J/(mol K)

• ∆x = vf∆t − 1/2 a(∆t) ² where ∆x = displacement, vf = is the final velocity, ∆t = elapsed time and a = acceleration.

• Wave = ∆x ∆t wave = displacement ∆t = average velocity ∆x = elapsed time.

• Coulomb constant, 1/4πε ₀ = 8.9875517923(14) × 10 ⁹ N m ² /C ²

• Permittivity of vacuum 0 = 8.85 × 10 ⁻¹² F/m

• Stefan-Boltzmann constant, σ = 5.67 × 10 ⁻⁸ W/(m ² K ⁴ )

• Mass of electron, m _e = 9.1 × 10 ⁻³¹ kg

• Faraday constant, F = 96485 C/mol

• p = mv

• Mass of neutron, m _n = 1.6749 × 10 ⁻²⁷ kg

• Mass of proton, m _p = 1.6726 × 10 ⁻²⁷ kg

• Standard atmosphere, atm = 1.01325 × 10 ⁵ Pa

• Rydberg constant, R _∞ = 1.097 × 10 ⁷ m ⁻¹

• Wien displacement constant, b = 2.9 × 10 ⁻³ m K

• Bohr radius, a ₀ = 0.529 × 10 ⁻¹⁰ m

• Bohr magneton, µ _B = 9.27 × 10 ⁻²⁴ J/T

• F = ma where m = mass, F = force, and a = acceleration Newton’s Second Law.

F is termed as the net force on the mass m.

• f = µN f = friction force, where N = normal force and µ = coefficient of friction.

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

• P = W ∆t P = power, where ∆t = elapsed time and W = work.

Power is the amount of work that is done per unit of time; that is, power is the rate at which work is done.

• V _avg = (vi + vf*) ² where vi = initial velocity and vf = final velocity.

• KE  = 1/2 mv ² K, where KE = kinetic energy, m = mass, v = velocity.

• ∆x = vi∆t + 1/2 a(∆t) where ∆x = the displacement, ∆t = the elapsed time, vi = the initial velocity, and a = the acceleration.

• W = mg, where m = mass, W = weight, and g = acceleration which is due to gravity.

Then, we weigh an object called mass, m. This is said to be Newton’s Second Law.

• W = F.d or W = F d cos θ, where W = work, d = distance, F = force, and θ = angle between F and the direction of motion.

• W = ∆(KE), where KE = kinetic energy and W = work done.

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, where E = total energy, KE = kinetic energy, and PE = potential energy.
