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.

Your Age on Other Worlds Want to melt those years away? Travel to an outer planet! <div class="js-required"><hr> This Page requires a Javascript capable browser <hr></div> Fill in your birthdate below in the space indicated. The Days (And Years) Of Our Lives Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. The earth is in motion. The top-like rotation of the earth on its axis is how we define the day. The revolution of the earth around the sun is how we define the year. We all learn in grade school that the planets move at differing rates around the sun. Why the huge differences in periods? Johannes Kepler Tycho Brahe Kepler briefly worked with the great Danish observational astronomer, Tycho Brahe. Here you see a planet in a very elliptical orbit. Kepler's third law is the one that interests us the most. Let's just solve for the period by taking the square root of both sides: The Gravity Of The Situation Isaac Newton ©2000 Ron Hipschman
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.

Forms of Energy Back to Table of Contents What are the different forms of energy? Energy has a number of different forms, all of which measure the ability of an object or system to do work on another object or system. In other words, there are different ways that an object or a system can possess energy. Here are the different basic forms: Kinetic Energy: Consider a baseball flying through the air. The formula for Kinetic energy, and for some of the other forms of energy described in this section will, is given in a later section of this primer. Potential Energy: Consider a book sitting on a table. Thermal, or heat energy: Consider a hot cup of coffee. Chemical Energy: Consider the ability of your body to do work. Electrical Energy All matter is made up of atoms, and atoms are made up of smaller particles, called protons (which have positive charge), neutrons (which have neutral charge), and electrons (which are negatively charged). Electrochemical Energy: Consider the energy stored in a battery. Sound Energy:

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.
