Wave Pendulum

Galileo Galilei and noted that the period of a Pendulum does not depend on the range of motion (at least when it comes to small oscillations), but the length of the thread; What happens then if multiple pendulums are placed whose length increases progressively? Well, they do a wave! The difference between them is incremented with each new swing, leading to an optical illusion. Finally, pendulums c..

Newton Pendulum

3rd law of Newton : " For every action there is an equal and opposite reaction " This law is very simple to show with this fascinating toy: Newton´s Pendullum.
