Stars.
Natural engines that generate heat and light energy are called stars, as a result of mass and gravity they start thermonuclear reactions (fusion), which heat the cores of stars to millions of degrees. These are the source of all energy in the universe after the big bang.
Machines that convert this heat energy into usable work are numerous. Simple machines like sails, windmills and waterwheels use the inherent motion of convective currents or gravity to move other machines by mechanical means. Other machines such as turbines (wind, steam or water) use this motive force to generate electricity by rotating a magnetic field through another stationary magnetic field, in a machine called a generator or an alternator.
Note: geothermal energy was created by accretion, a frictional heat release caused by the striking of large bodies into the Earth. Because all material in the universe was created by the fusion engines in stars and the eventual destruction of large stars, nuclear radiation (from radioisotopes) was along with this geothermal energy a byproduct of the basic fusion generating the energy inside the stars.
*Fossil fuels were mostly vegetation, which had converted solar energy and carbon dioxide into sugars and oxygen, by photosynthesis, which later died, compacted and transformed into hydrocarbons, which release their energy when burned.
What else can I help you with?
What energy sources are used for modern machines such as cars and sewing machines?
idk u guess
How is energy needed to make machine work?
Energy is needed to make machines work because it powers the movement and function of the various components within the machine. This energy can come from sources such as electricity, fuel, or human input, and is converted into the mechanical energy needed to operate the machine. Without energy, machines would not be able to function and perform their intended tasks.
Can machines increase energy?
Machines themselves cannot inherently create energy; they can only convert energy from one form to another. Machines can be used to harness energy from different sources such as fossil fuels, wind, or solar power, but they cannot create energy on their own.
What is the energy that you use to run many machines?
Electricity is the energy used to power many machines. It is a versatile and widely-used form of energy that is generated from a variety of sources such as coal, natural gas, nuclear power, and renewable sources like wind and solar.
What is the form of energy of familiar objects and machines?
Familiar objects and machines can have various forms of energy, such as electrical energy (from batteries or power sources), mechanical energy (from movement or stored in springs), thermal energy (from heat sources), and potential energy (stored energy based on position or configuration).
How you will derive energy to run your machines where there are no fossil fuels?
From renewable sources of energy like solar, wind, hydro, geothermal and many others.
How do machines create energy?
It is wrong to say machines create energy. Machines have to be given energy to make them effective. This could be electric energy, solid liquid or gaseous energy, thermal energy, mechanical energy (like a flywheel for example). It may be possible to design machines which will search for their energy by themselves, some robots may already have achieved. Remember we humans are also machines, but we get our energy from digesting food.
What are 3 of the sources of energy that can make matter emit light?
Sources of energy that can make matter emit light include heat energy (thermal radiation), electrical energy (electric discharge), and chemical energy (luminescence from chemical reactions).
What are the ways to make sure there will be enough energy for the future?
In the most general terms, that would be: (1) Find new energy sources or make better use of the existing energy sources; and (2) Use less energy.
What is the application of energy?
Energy is used in many applications, such as lighting, heating, transportation, and industrial processes. It is essential for powering our daily activities and the functioning of machines and technology. Sources of energy can include fossil fuels, renewable sources like solar and wind, and nuclear power.
What is the definition of obtaining energy?
Obtaining energy refers to the process of acquiring or harnessing energy from various sources, such as food, sunlight, or fuel, to power the activities and functions of living organisms or machines. It involves converting the stored energy in these sources into a form that can be used to perform work or sustain life processes.
Can a machine make energy?
No, machines cannot create energy. Instead, machines can convert one form of energy into another, such as a generator converting mechanical energy into electrical energy. The law of conservation of energy states that energy cannot be created or destroyed, only transformed.
