Newton's cradle demonstrates conservation of momentum and energy
Material required:Equally weighted Ball, String, Stand etc.
Description:A
typical Newton's cradle consists of a series of identically sized metal balls
suspended in a metal frame so that they are just touching each other at rest.
Each ball is attached to the frame by two wires of equal length angled away
from each other. This restricts the pendulums' movements to the same plane.
