Elastic collisions conserve both momentum and kinetic energy. Objects bounce without deforming, maintaining the system's total mechanical energy.
Trin-for-trin guide
- 1Enter masses and velocities of two colliding objects
- 2The calculator applies conservation of momentum and energy
- 3Results show final velocities after collision
Løste eksempler
Input
m₁ = 1 kg, v₁ = 5 m/s, m₂ = 1 kg, v₂ = 0 m/s
Resultat
v₁_final = 0, v₂_final = 5 m/s
Complete velocity exchange (equal mass)
Almindelige fejl at undgå
- ✕Forgetting to conserve both momentum and energy
- ✕Using energy conservation alone (which also applies to inelastic collisions)
Ofte stillede spørgsmål
Are elastic collisions common?
Perfectly elastic collisions are rare; they approach reality in hard material interactions like billiard balls or atomic particles.
What if masses are very different?
Heavy objects barely slow down hitting light ones; light objects bounce back at nearly double the impact speed.
