Understanding This Calculator

Nuclear Physics Formulas

Equations for decay and energy.

  • Decay: N(t) = N₀ × e^(-λt)
  • Half-Life: T½ = ln(2) / λ ≈ 0.693 / λ
  • Energy: E = mc²

Example 1 (Half Life)

λ = 0.1 s⁻¹

  • T½ = 0.693 / 0.1 = 6.93 s

Example 2 (Energy)

Mass Defect: 1u (1.66e-27 kg)

  • E = 1.66e-27 × (3e8)² ≈ 1.49e-10 J

How to Use

  • Enter initial amount and decay constant for radioactive decay.
