The physics calculator hub covers mechanics, waves, electricity, thermodynamics, and modern physics — from basic F=ma to quantum energy calculations.

Formule

Kinematics: v = u + at; s = ut + ½at²; v² = u² + 2as

v: fλ; Photon energy E=hf — fλ; Photon energy E=hf
s: ut + ½at²; v² = u² + 2as — ut + ½at²; v² = u² + 2as

Guide étape par étape

1Kinematics: v = u + at; s = ut + ½at²; v² = u² + 2as
2Energy: KE = ½mv²; GPE = mgh; Work = Fd×cos(θ)
3Electricity: V=IR; P=IV; E=Pt
4Waves: v=fλ; Photon energy E=hf
