__Basic Physics Formula Part - 2__

## Electromagnetism:

✅ F = qE (force on a charged particle equals the charge times electric field strength)

✅ F = Bqv (force on a charged particle moving through a magnetic field equals magnetic field strength times charge times velocity)

✅ V = IR (Ohm's law - voltage equals current times resistance)

## Fluid Mechanics:

✅ F = rho * g * V (buoyant force equals density times gravity times volume)

✅ P1 + 1/2 * rho * v1^2 + rho * g * h1 = P2 + 1/2 * rho * v2^2 + rho * g * h2 (Bernoulli's equation - pressure plus kinetic energy plus potential energy equals constant)

## Atomic and Nuclear Physics:

✅ E = mc^2 (mass-energy equivalence - energy equals mass times the speed of light squared)

✅ lambda = h/p (de Broglie wavelength - wavelength equals Planck's constant divided by momentum)

✅ N = N0 * e^(-lambda*t) (radioactive decay - number of radioactive nuclei equals initial number times e to the negative decay constant times time)

## Quantum Mechanics:

✅ E = hf (Planck-Einstein relation - energy of a photon equals Planck's constant times its frequency)

✅ p = h/lambda (de Broglie's equation - momentum equals Planck's constant divided by wavelength)

✅ HΨ = EΨ (Schrödinger's equation - the wave function Ψ of a system satisfies the time-independent Schrödinger's equation HΨ = EΨ, where H is the Hamiltonian operator and E is the energy of the system)

## Electromagnetic Waves:

✅ c = f * lambda (speed of light equals frequency times wavelength)

✅ E = hc/lambda (energy of a photon equals Planck's constant times the speed of light divided by wavelength)

✅ B = E/c (magnetic field strength equals electric field strength divided by the speed of light)

## Modern Physics:

✅ V = c^2 / sqrt(1-v^2/c^2) (relativistic velocity addition - velocity in one frame equals the velocity in another frame plus the velocity of the two frames divided by the speed of light squared)

✅ E = mc^2 + K (total energy of a particle equals its rest energy plus its kinetic energy)

✅ N = N0 * e^(-λt) (radioactive decay - number of radioactive nuclei equals the initial number times e to the negative decay constant times time)

## Special Relativity:

✅ t' = t/sqrt(1-v^2/c^2) (time dilation - time in a moving frame equals time in a rest frame divided by the square root of 1 minus velocity squared over the speed of light squared)

✅ L = L0 * sqrt(1-v^2/c^2) (length contraction - length in a moving frame equals length in a rest frame times the square root of 1 minus velocity squared over the speed of light squared)

✅ E = gamma * mc^2 (relativistic energy - energy equals the rest mass times the speed of light squared times the gamma factor)
