Elastic Collision

Observe 1D elastic collisions between two objects. Both momentum and kinetic energy are conserved. Adjust masses and velocities to explore different outcomes.

Object 1 (Blue)

Mass (m₁) 2.0 kg

Velocity (v₁) 5.0 m/s

Object 2 (Green)

Mass (m₂) 3.0 kg

Velocity (v₂) -3.0 m/s

Formulas

v₁' = ((m₁-m₂)v₁ + 2m₂v₂) / (m₁+m₂)

v₂' = ((m₂-m₁)v₂ + 2m₁v₁) / (m₁+m₂)

Σp = m₁v₁ + m₂v₂ = const

ΣKE = ½m₁v₁² + ½m₂v₂² = const
