How a Pogo Stick Works The pogo stick is a mechanical device that utilizes the spring’s ability to store energy. In this paper I will explain how the toy uses the laws of physics to provide hours of fun. There are a lot of forces acting on you and the pogo stick as you bounce along. We’ll take an in depth look at all of these forces and what part they play in the overall functioning of pogo sticks. The physical aspects can be broken down into sections to get a better understanding of what is going

moving through the stationary phase‚ it picks up compounds that need to be tested‚ taking those compounds with it. Through adsorption‚ the mobile phase separates into different components (soinc). The mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their
