⚡ Newton's Cradle (2D)

Lift balls on one side — the same number fly out the other. Momentum p = m·v is conserved through the elastic collision chain.

Lift from left

Lift from right

Balls = 5

Damping = 5%

String length = 130

Bounces: 0

⚡ p = m·v
Momentum is conserved! Lift N balls → N balls fly out the other side.
