This post has been sitting in my mind for quite some time. Really, it is about mechanics - not about pendulums. What is the goal in mechanics (classical mechanics, if you like)? Generally, it is to ...

Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. For example, in order to lift a heavy object, we must do work to overcome ...

A ball is suspended from a pivot so that it can swing freely. The length of the pendulum is adjustable. For small amplitude, the motion of the pendulum as a function of time is approximately simple ...

Michael Graham Richard is a writer from Ottawa, Ontario. He worked for Treehugger for 11 years, covering science, technology, and transportation. So what is kinetic energy? There's motion everywhere ...
