Inelastic collisions conserve momentum but not kinetic energy. Objects stick together or deform, with lost energy converting to heat and deformation.

Formule

The calculator conserves momentum: m₁v₁ + m₂v₂ = (m₁ + m₂)v_final

Guide étape par étape

  1. 1Enter masses and velocities of colliding objects
  2. 2The calculator conserves momentum: m₁v₁ + m₂v₂ = (m₁ + m₂)v_final
  3. 3Results show final velocity and energy loss

Exemples résolus

Entrée
m₁ = 1 kg, v₁ = 10 m/s, m₂ = 1 kg, v₂ = 0 m/s (perfectly inelastic)
Résultat
v_final = 5 m/s, ΔKE = 25 J lost
Momentum conserved, energy not

Erreurs courantes à éviter

  • Attempting to conserve kinetic energy (it's not conserved)
  • Calculating final velocity incorrectly using separate masses

Questions fréquentes

Why is kinetic energy not conserved?

Energy transforms into deformation, heat, sound, and other forms; the total energy is still conserved.

What's a perfectly inelastic collision?

Objects stick together after collision, representing maximum possible energy loss while still conserving momentum.
