## Physics Formulas Every NEET Aspirant Must Master

Physics is an essential subject in the NEET exam, and mastering key formulas is crucial for success. Here are some important physics formulas that every NEET aspirant should focus on.

A) Newton’s Second Law: F = ma (Force equals mass times acceleration)

B) Gravitational Force: F = G (m1 * m2) / r^2 (Newton’s law of universal gravitation)

C) Kinematic Equations: Various equations for motion, such as: v = u + at (final velocity = initial velocity + acceleration * time) s = ut + (1/2)at^2 (displacement = initial velocity * time + 0.5 * acceleration * time^2).

A) Work-Energy Theorem: W = ∆KE (Work done equals the change in kinetic energy)

B) Kinetic Energy: KE = (1/2)mv^2

C) Potential Energy (Gravitational): PE = mgh (mass * gravitational acceleration * height)

D) Power: P = W/t (Power equals work done per unit time)

A) First Law of Thermodynamics: ∆U = Q – W (Change in internal energy equals heat added minus work done)

B) Ideal Gas Law: PV = nRT (Pressure * Volume = moles * gas constant * temperature)

A) Coulomb’s Law: F = (k * |q1 * q2|) / r^2 (Electric force between two charges)

B) Electric Field: E = F/q (Electric field strength)

C) Electric Potential Energy: U = k * (q1 * q2) / r (Potential energy of two charges)

A) Ohm’s Law: V = IR (Voltage equals current times resistance)

B) Power in Electric Circuits: P = IV (Power equals current times voltage)

A) Magnetic Field: B = μ₀I / (2πr) (Magnetic field due to a current-carrying wire)

B) Magnetic Force on a Moving Charge: F = qvB (Magnetic force on a charged particle moving in a magnetic field)

C) Faraday’s Law of Electromagnetic Induction: ∆Φ = -N * ∆B/∆t (Change in magnetic flux induces an electromotive force)

A) Snell’s Law: n₁sinθ₁ = n₂sinθ₂ (Law of refraction)

B) Lens Formula: 1/f = 1/v – 1/u (Relation between focal length, object distance, and image distance)

C) Mirror Formula: 1/f = 1/v + 1/u (Relation between focal length, image distance, and object distance)

A) Einstein’s Mass-Energy Equivalence: E = mc² (Energy-mass equivalence)

B) de Broglie Wavelength: λ = h / p (Wavelength associated with a particle)

C) Planck’s Quantum Theory: E = hf (Energy of a photon)

These are some of the fundamental physics formulas that you should master for the NEET exam. However, remember that understanding the concepts behind these formulas is equally important. Practice solving problems and applying these formulas in various contexts to ensure a strong grasp of physics concepts and their applications.
