Forces and Toques in Equilibrium
Abstract
In this experiment we will use the principle of rotational equilibrium to create a simple mass scale using
a meter stick. We will investigate the concept of center of gravity and torque an

What is a storm? We've determined that swells are made by wind, and wind comes
from storms. But what really is a storm? Well, let's start with some basics. Air covers the
surface of our planet and has mass, that is, it has weight and volume, and it can be
