Explain how Newton's cradle demonstrates the law of conservation of energy.

Newton's cradle demonstrates the law of conservation of energy as follows:

A tool named after the most popular scientist Sir Issac Newton, which utilizes a bunch of spinning balls to illustrate momentum and energy conservation, which is understood as Newton's cradle. Here the experiment involve hitting of the stationary ball as one ball is raised and released at the end, transmitting a force through the stationary ball that forces the last sphere upward.

This illustrates the theory of momentum conservation (mass time speed), which says that the total momentum of the objects prior to the actual collision is equal to the total momentum of the entities after the collision, if two entities clash.

The constant banging of balls is also evidence of Newton's energy conservation law, which notes that energy can not be produced or destroyed but can switch ways. Also reveals this last aspect of the law very well, as it transforms one ball's potential energy into kinetic energy which is converted down the line of balls and eventually contributes to the last ball's upward swing.
