this article‚ we’ll see how these parts come together to produce bright light for hours on end. Light Basics Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles‚ called light photons‚ are the most basic units of light. (For more information‚ see How Light Works.) Atoms release light photons when their electrons become excited. If you’ve read How Atoms Work‚ then you know that electrons

city-states. As we know‚ catapults were mainly used in the medieval era‚ or rather‚ it is most famous for use in that time‚ which you have probably seen in movies and books. How Does the Catapult Work? There is quite a bit of science behind the making of the catapult‚ and how it works. It is similar to a ballista that it works by storing tension in a flexed piece of wood or in twisted ropes. It’s similar to a bow‚ but on a much larger scale. However‚ that is just the catapult which is probably most

HOW AN ELECTRIC GENERATOR WORKS Electrical generators by definition are devices that convert mechanical energy into electric energy. The mechanical energy in turn is produced from chemical or nuclear energy in various types of fuel‚ or obtained from renewable sources such as wind or falling water. Steam turbines‚ internal-combustion engines‚ gas combustion turbines‚ electric motors‚ water and wind turbines are the common methods to supply the mechanical energy for such devices. Generators

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

How Does the Thermometer Work? A thermometer is a device that measures the temperature of things. The name is made up of two smaller words: "Thermo" means heat and "meter" means to measure. You can use a thermometer to tell the temperature outside or inside your house‚ inside your oven‚ even the temperature of your body if you’re sick. One of the earliest inventors of a thermometer was probably Galileo. We know him more for his studies about the solar system and his "revolutionary" theory

NOVA: How the Brain Works The description pretty much describes this video well. In essence‚ it’s a look into the complexity of the human brain. Trying to understand how we perceived the world around us and showing some of the experiments that try to explain how the process works. If you want to spend an hour with quirky but interesting approach to the topics of how illusions work‚ how our brains are affected by electro-magnetic impulses and what is the current status of artificial intelligence
