I can calculate the motion of heavenly bodies but not the madness of people. — Isaac Newton.


Fun with springs


The applications of a simple harmonic oscillator are almost endless. You may be surprised though to find out what happens when you drop such a simple harmonic oscillator!!

Ball drop
Ball being dropped onto a spring.
Slinky drop

Can you guess which part of the slinky is going to move first, if any?
