1D Collisions

Elastic and inelastic collisions. Adjust masses, velocities, and coefficient of restitution.

m₁2.0 kg

m₂1.0 kg

v₁4.0 m/s

v₂-1.0 m/s

e (restitution)1.00

Before: 0.000 kg·m/s

After: 0.000 kg·m/s

Conserved (within numerical error)

Before: 0.000 J

After: 0.000 J

Elastic — KE conserved

Equations

v₁′ = (u₁(m₁−e m₂) + u₂ m₂(1+e)) / (m₁+m₂)

v₂′ = (u₂(m₂−e m₁) + u₁ m₁(1+e)) / (m₁+m₂)

p = m₁v₁ + m₂v₂ (conserved)

e = 1 elastic · e = 0 perfectly inelastic
