Energy

A dynamo is an electric generator. The basic principle is that, when a wire (or any conductor, for that matter) moves through a magnetic field, a voltage is is induced across the wire. This will cause current to flow.

Water can be transformed into usable energy through hydropower, where the kinetic energy of flowing water is converted into mechanical energy by a turbine, which then drives a generator to produce electricity. This process is commonly used in hydroelectric power plants to generate clean and renewable energy.

The Sun is the largest source of energy on Earth, providing heat and light through processes like nuclear fusion. This energy is harnessed for various purposes, such as generating electricity through solar panels and driving weather patterns through the Earth's climate system.

Organisms like plants use sunlight through photosynthesis to make energy, while animals and other organisms consume food to obtain energy through processes like respiration or fermentation.

You could start by realizing how much it would cost. LEDs are very efficient, and have very long life spans (typically 100,000 hours +), but cost a lot to initially install. Our cities highschools (two schools with around 3,000 students each) just got a very large bond passed (somewhere around 10 mil) and they upgraded everything in one, and rebuilt the second. 70" plasmas in each room, and a state of the art library that ranks in the top 25 in the US. None of the lights are LED. they are however the less costly alternative; flurocents. Most if not all commercially used building (including schools) already have these systems in place. Depending on the age of the school, they may have aging systems that need to be updated, which is fairly inexpensive, opposed to installing banks of LEDs (rows of LEDs - necessary to provide even light, as they don't distribute light i

n wide angles.) which would cost a fortune (a simple basic LED bulb from radio shack: 50-75¢ last I saw. Now multiply that by say 200 for each bank of LEDs. How many banks would u need? Count the existing amout of light fixtures in the school, and that's about how many you need.). Our school has around 4,000 fixtures (3 floors; 30 rooms each floor, 10 fixtures per room. Science wing; 50 rooms (induing labs), 10 fixtures each. Hallways: 75 per floor. Gym; 100 large fixtures (equals 4 banks of LEDs each fixture) Basketball court; 75 large fixtures (same size as gym's). Cafeteria; 50 fixtures. Main entrance; 75 fixtures. Music wing; (20 large rooms) 25 fixtures per room. Auditorium; 200 fixtures. -- just to give you an idea on how many lights for each kind of rooms and such.) so 4,000 x 200 = 800,000. 800,000 x 50¢ = $400,000. Then add in the price of the LED fixtures (things that hold the LEDs): about $50 per fixture; so 4,000 x $50 = $200,000. Now add in labor; $200,000 to have permits, and a large work force to get it done fast and well. So you have a grand total of: $400,000 + $200,000 + $200,000 = $800,000. LEDs vs. Fluorescent energy consumption is notable, but it could take decades to pay for itself, and really not have a big "green" effect your going for. In otherwords: your not going go convince them unless you give them an insane amount of money. If your looking to go green; try researching the benefits of geothermal heating/cooling, depending on where you live. And present that to your school board. I'm sure you school still uses boiler rooms; very inefficient. (our school also uses geothermal as well). Sorry that was so long, but I had to make sure you understood the price vs outcome. But do look for other ways for you school to go green! It's Great thing to do for you community!

kinetic energy is energy in motion. potential is like a roller coaster you start at the bottom and go up to highest point of the coaster and yougain potential energy as you move to the highest point of the coaster and when you go down the peak point the potential energy the coaster was gaining is transferred to kinetic energy.

This concept is known as natural selection, a key mechanism of evolution proposed by Charles Darwin. Organisms with traits that provide them with a survival advantage in their environment are more likely to survive, reproduce, and pass on these advantageous traits to their offspring. Over time, this process leads to the gradual accumulation of beneficial traits in a population.

No, solar power is not a form of geothermal energy. Solar power is generated by converting sunlight into electricity using solar panels. Geothermal energy, on the other hand, harnesses heat from beneath the Earth's surface to generate electricity or heat buildings.

Limestone transforms into marble through a process called metamorphism, which occurs when limestone is subjected to high temperatures and pressures over time. The heat and pressure cause the calcite crystals in limestone to recrystallize and grow larger, resulting in a denser, harder rock with a distinct crystalline structure and a variety of colors and patterns.

The arrow acquires kinetic energy when it is released from the bow and begins to move through the air. At this point, the stored potential energy in the bow limbs is converted into kinetic energy as the arrow accelerates forward.

Geothermal energy is better than coal because it is a renewable energy source that produces minimal greenhouse gas emissions. Geothermal energy is considered more sustainable and environmentally friendly compared to coal, which is a fossil fuel that contributes significantly to air pollution and climate change. Additionally, geothermal energy has a smaller environmental footprint and is not dependent on mining or transportation of fuel sources.

Energy passes from one living thing to another through a food chain or food web. Producers, such as plants, convert sunlight into energy through photosynthesis. This energy is then consumed by herbivores, which are in turn consumed by carnivores or omnivores.

Yes, you can subtract a megawatt from a gigawatt because they are both units of power but differ by a factor of 1000. One gigawatt is equivalent to 1000 megawatts, so subtracting one megawatt from a gigawatt leaves you with 999 megawatts.

One disadvantage of using gas hydrates is that they are difficult and expensive to extract in large quantities. The technology for extracting gas hydrates is still under development and may not be commercially viable yet. Additionally, there are concerns about the potential environmental impact of extracting gas hydrates, as it could release methane, a potent greenhouse gas, into the atmosphere.

Kinetic energy can be coverted to electrical energy. This happens in power stations when turbines turn (kinetic) to generate electricity. There are other applications that transfer kinetic energy to electrical energy such as dynamos.

Sometimes the kinetic energy is converted to stored energy like strain or gravitational energy. Winding something up for example, this energy can then be used to power watches, wind up toys and even wind up radios.

Kinetic energy is also converted into heat and sound - rub your hands together and you'll see what I mean!

The primary energy source for Earth's weather systems is the Sun. Solar radiation heats the Earth's surface, creating temperature differences that drive atmospheric circulation and weather patterns. Other factors, such as the Earth's rotation and the distribution of land and sea, also play a role in shaping weather systems.

heat, when burnt kinetic, when burnt can turn a turbine light, when burnt, lets off light

Plasma typically has the most energy of all the phases of matter. Plasma consists of ionized particles that move freely and can reach extremely high temperatures, making it the most energetic state of matter.

they redirect the magnetic field. for instance, a material known as mu-metal attracts all of the magnetism to it, thus redirecting the magnetic field away form other stuff. kinda like a faraday shield redirects electrons, mumetal redirects magnetism.

the basic principal here is that some materials "want" magnetism more than others. thus you can put the magnet near it, and it will "hog" all of the magnetism. hope that's scientific enough :)

Geothermal power stations have advantages such as being renewable, reliable, and producing low greenhouse gas emissions compared to fossil fuels. They also have a small physical footprint and can provide a constant source of energy.

Friction can produce heat, but it alone cannot be used to charge a device. Friction converts kinetic energy into thermal energy, which dissipates into the surroundings. To charge a device, you would need a source of energy that can be converted into electrical energy, such as solar power, wind power, or chemical energy in a battery.

Geothermal energy is derived from the Earth's internal heat, not from the sun. This heat is created by the decay of radioactive elements in the Earth's core and is trapped beneath the Earth's surface, making it independent of solar energy.
