Essential Physics Formulas
Key equations from mechanics, electricity, thermodynamics, and modern physics.
Newton's Second Law
MechanicsForce equals mass times acceleration.
F = force (N), m = mass (kg), a = acceleration (m/s²)
Kinetic Energy
MechanicsEnergy of an object due to its motion.
KE = kinetic energy (J), m = mass (kg), v = velocity (m/s)
Ohm's Law
ElectricityVoltage equals current times resistance.
V = voltage (V), I = current (A), R = resistance (Ω)
Wave Speed
Waves & SoundWave speed equals frequency times wavelength.
v = wave speed (m/s), f = frequency (Hz), λ = wavelength (m)
Ideal Gas Law
ThermodynamicsRelates pressure, volume, moles, and temperature of an ideal gas.
P = pressure (Pa), V = volume (m³), n = moles, R = gas constant, T = temperature (K)
Mass-Energy Equivalence
Modern PhysicsEnergy and mass are interchangeable, scaled by the speed of light squared.
E = energy (J), m = mass (kg), c = speed of light (3×10⁸ m/s)
