Coaster Creator | The JASON Project Coaster Creator is an interactive game that explores the science behind roller coasters. Use your knowledge of potential energy and kinetic energy to design your own coaster. Rapid energy transfer is the key to roller coaster thrills but be careful – too much kinetic energy and you’ll crash, too little and you’ll stall. Important Words in this Resource: potential energy, kinetic energy, friction, thermal energy, sound energy, energy conversion, energy transformation, energy conversions, Argonaut, Vasily Titov, rollercoaster, roller coaster, digital lab, game States of Matter Topics Atomic Bonding Interaction Potential States of Matter Dipole Description Watch different types of molecules form a solid, liquid, or gas. Sample Learning Goals Describe a molecular model for solids, liquids, and gases.Extend this model to phase changes.Describe how heating or cooling changes the behavior of the molecules.Describe how changing the volume can affect temperature, pressure, and state.Relate a pressure-temperature diagram to the behavior of molecules.Interpret graphs of interatomic potential.Describe how forces on atoms relate to the interaction potential.Describe the physical meaning of the parameters in the Lennard-Jones potential, and how this relates to the molecule behavior.

Internal Combustion" The principle behind any reciprocating internal combustion engine: If you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. You can use that energy to propel a potato 500 feet. In this case, the energy is translated into potato motion. You can also use it for more interesting purposes. For example, if you can create a cycle that allows you to set off explosions like this hundreds of times per minute, and if you can harness that energy in a useful way, what you have is the core of a car engine! Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. Intake strokeCompression strokeCombustion strokeExhaust stroke Figure 1 You can see in the figure that a device called a piston replaces the potato in the potato cannon. Now the engine is ready for the next cycle, so it intakes another charge of air and gas.

Coaster Welcome to the death defying Funderstanding Roller Coaster! This simulator is designed for people who want to design their own thrilling coaster and educators who want to use a cool activity to simulate the application of physics by using an exciting interactive tool and access to a wonderful reference source. It is your mission to become a roller coaster designer so that you can achieve maximum thrills and chills without crashing or flying off the track (unless that’s how you like your coaster to work!). If you accept this mission you must decide on a number of factors. You are responsible for setting the controls for the height of hill #1, hill #2, the size of the loop, the initial speed of the coaster, its mass, the gravity at work and the amount of friction on the track. This great educational online tool offers an interactive way for kids to play a roller coaster game, and learn while doing it. Finally, some fun online education kids!

The Electromagnetic Spectrum - Index page The electromagnetic spectrum is more familiar to you than you might think. The microwave you use to heat your food and the cell phones you use are part of the Electromagnetic Spectrum. The light that our eyes can see is also part of the electromagnetic spectrum. This visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow - from reds and oranges, through blues and purples. Each of these colors actually corresponds to a different wavelength of light. Alternative fuel vehicle An alternative fuel vehicle is a vehicle that runs on a fuel other than "traditional" petroleum fuels (petrol or diesel); and also refers to any technology of powering an engine that does not involve solely petroleum (e.g. electric car, hybrid electric vehicles, solar powered). Because of a combination of factors, such as environmental concerns, high oil prices and the potential for peak oil, development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world. Hybrid electric vehicles such as the Toyota Prius are not actually alternative fuel vehicles, but through advanced technologies in the electric battery and motor/generator, they make a more efficient use of petroleum fuel.[1] Other research and development efforts in alternative forms of power focus on developing all-electric and fuel cell vehicles, and even the stored energy of compressed air.

Español How Do Solar Panels Work? share By Stephanie Chasteen and Rima Chaddha Posted 04.24.07 NOVA We've seen them for years on rooftops, atop highway warning signs, and elsewhere, but how many of us know how solar panels actually work? How do the photovoltaic cells that lie at the heart of them turn sunlight ("photo") into electricity ("voltaic")? In this feature, familiarize yourself with the parts of a basic photovoltaic cell, and find out how it goes about harnessing the free energy of the sun. This feature originally appeared on the site for the NOVA program Saved By the Sun. Stephanie Chasteen is a postdoctoral fellow in physics at the Exploratorium in San Francisco.

Alternative Fuel Vehicles Alternative fuels are derived from resources other than petroleum. Some are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources. Often, they produce less pollution than gasoline or diesel. Ethanol is produced domestically from corn and other crops and produces less greenhouse gas emissions than conventional fuels. Biodiesel is derived from vegetable oils and animal fats.

Alkaline battery Alkaline batteries Compared with zinc-carbon batteries of the Leclanché or zinc chloride types, alkaline batteries have a higher energy density and longer shelf-life, with the same voltage. Button cell silver-oxide batteries have higher energy density and capacity but also higher cost than similar-size alkaline cells. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, instead of the acidic ammonium chloride or zinc chloride electrolyte of the zinc-carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes. Alkaline batteries account for 80% of manufactured batteries in the US and over 10 billion individual units produced worldwide. Alkaline batteries are used in many household items such as MP3 players, CD players, digital cameras, pagers, toys, lights, and radios, to name a few.
