Nuclear energy is produced in much the same way that electricity is produced by other power plants; the splitting of atoms creates heat, turning water into steam, and then the pressure of the steam turns the generator with the end product being electricity. The process of splitting atoms is known as nuclear fission, and it is nuclear fission that replaces the fossil fuels of coal, natural gas or oil that are normally used to produce electricity in traditional power plants.Know More
In a nuclear power plant, nuclear energy is created when a nuclear reactor creates heat. The heat is used for making steam. The steam is used to turn a turbine that is connected to a generator, which is essentially an electromagnet. The generator produces electricity that is then routed to customers' homes.
Uranium is the type of fuel that is used in nuclear fission. Inside pellets of uranium fuel reside millions of uranium nuclei that are split during nuclear fission. This splitting sets off the release of a huge amount of energy; most of it is from kinetic energy, but some is from radiation. The kinetic energy produces the heat inside the nuclear reactor that produces steam and in the end, electrical power.Learn more about Motion & Mechanics
Steam is produced by a boiler in the engine, which is then sent into a cylinder that contains a piston onto which the steam puts pressure until it moves and in turn moves the machinery attached to it. Once the piston has moved its full cycle, a valve opens releasing the cooler steam out into the air outside of the cylinder. This release of steam allows the piston to return to its original position so that the process can be completed.Full Answer >
A pressure gauge allows a fluid to enter from the item or equipment being measured and reacts by moving a calibrated rod inside it. The pressure can be correctly read when the rod has moved to its maximum position.Full Answer >
Water energy works by powering turbines that turn generators to produce electricity. Turning the turbines requires water movement, such as rivers flowing downstream, waves or tide changes. In addition, scientists are working on methods of removing heat energy from the ocean water.Full Answer >
The work-energy theorem is a generalized description of motion that states that the work done by the sum of all forces acting on an object is equal to the change in that object's kinetic energy. This principle of work and its relationship to kinetic energy is a core mechanical physics concept.Full Answer >
