Mb-2 Newton's Cradle

Aim

To demonstrate the conservation of momentum and energy laws.

Apparatus

  • Newton's Cradle

Newton's Cradle Newton's Cradle Diagram

Newton's Cradle and Diagram.

Description

For small displacements we essentially have linear motion, and, hence conservation of momentum. Together with the conservation of energy law, it can be shown that if m balls are used to give an impulse to the system, then, following the collision, m balls will leave with equal momenta.
