Important Physics Formulas for NEET 2023

Physics concepts are backed by formulas and logical reasoning. So, to gauge a topic better, one has to be aware of all the Physics formula for NEET. Here are some crucial Physics formulas for NEET 2023 that one must refer to:

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

• Gravitation constant, G = 6.67×10⁻¹¹ m³ 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 × 10²³ 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, 1/4πε₀ = 8.9875517923(14) × 10⁹ N m²/C²

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

• Stefan-Boltzmann constant, σ = 5.67 × 10⁻⁸ W/(m² K⁴)

• 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 × 10⁵ Pa 

• Rydberg constant, R_∞ = 1.097 × 10⁷ m⁻¹

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

• Bohr radius, a₀ = 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 the termed as 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 which 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 mv² 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 have the weight of 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’ which 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.

How to Study Physics Formulas for NEET 2023 Correctly

Candidates can study NEET Physics formulas the right way by following these techniques.
