My topic for the science fair project is "The effect of temperature in energy loss in a basketball". Some of my subtopics for my project include the pressure air and height in a basketball‚ the material a basketball is made out of and the size of the ball. Different sports require different size balls to correspond with the correct bounce it needs to be used during the sport. Thats why you would not be able to use a tennis ball to play basketball because it is too bouncy and a soccer

The conversion of potential energy to kinetic energy is what drives the roller coaster‚ and all of the kinetic energy you need for the ride is there once the coaster goes down the very first hill. Once the coaster gets going‚ there are different types of wheels that help keep the ride smooth. Roller coasters don’t have engines. But they do have energy. Once all passengers are in the coaster‚ the carts get released and begin to roll down the first hill. The force of gravity makes them accelerate downwards

passages of "The Dangerous Delusions Of Energy Independence" Robert Bryce (Writing and Reading Across the Curriculum Brief Edition Behrens and Rosen 201-205) America loves the idea of independence. Their symbol is freedom‚ so they’d like to be as independent as they possibly can especially with the dangers that are involved with imported oil and gas. In 1974 president Richard Nixon had made a promise to America that they would work their way into being an energy independent country in a matter of 6

Kyle Smyre June 6 2011 Period 2 Mr. Watts Our Energy Future Currently‚ it’s clear that there is an immense problem with the prospect of society’s energy needs for the future. Such a large dependency on limited fossil fuels are already dampening the world’s economy‚ and following this path will simply ensure a destitute future. However‚ changes could be made in today’s time to prevent such an event from occurring‚ but it will require many separate state entities to work together and no longer

From the viewpoint of Seitz (2008)‚ solar energy source is widely seen as one of solutions with the greatest potential. In modern technology‚ according to Fanchi (2005)‚ heating and cooling system and solar electric generating system are associated with the solar energy industry at present. For instance‚ that solar heating collector which belongs to heating and cooling system can transform radiant energy into heat energy by capturing sunlight. Moreover‚ solar electric generating system is divided

From those values we compute for the work and the gravitational potential energy of that table. For the work done we use the formula w=mg L 1-cosθ and

Conservation of Energy In explaining the laws of conservation of energy‚ energy cannot be destroyed or made. Although‚ energy can be transformed or transferred from one form to another‚ for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned‚ and then used as thermal energy for heat‚ next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy‚ gravitational energy‚ electromagnetic

Renewable Energy: Yes or No? Joanna Fain Eng. 122 English Composition II April 15th‚ 2013 Although fossil fuels provide an inexpensive form of energy‚ they have been shown to pollute ecosystems‚ endanger animals and humans‚ are not sustainable‚ and cannot provide nearly the amount of energy that can be obtained from renewable sources. Fossil fuels do provide an inexpensive form of energy‚ but in contrast‚ they also pollute the atmosphere with greenhouse gases‚ thus contributing

Solar Energy‚ usually refers to the sun radiation Energy‚ in the modern society‚ generally used for power generation. Since the earth created creatures‚ those creatures depended on the heat and light of the sun‚ band also human beings knew to dry the objects in the sunlight‚ by which they kept food‚ such as salt-making and drying of salted fish‚ etc. But with the reduction of fossil fuel resources‚ then people are disposed to develop solar energy further. The methods of solar energy using include
