    Summary When a force displaces, work is said to be done. The force should be the net force and there should be a net displacement of the object. Work done by force acting on an object in the direction of the force is equal to the product of the magnitude of the force and the displacement covered by the object in the direction of the force. The work done is measured in joule in the SI system after the scientist James Prescott Joule. Erg is the CGS unit of work. Conditions for work to be...

    Energy Conservation Energy conservation is the reduction of quantity of energy used. Energy conservation supports the eco friendly lifestyle by providing energy, which saves your money and at the same time saves the earth. When you decrease the amount of energy you use you automatically make efforts to reduce increasing global warming.

    Physics Energy Exploration Project Energy can be stored in many forms as potential energy. It can be extracted through chemical and mechanical processes to get usable energy. We use that kinetic energy and electricity every day to power our lights, run our cars and do most of our tasks. Fossil Fuel is a non-renewable energy source. It results from the decomposition of dead and buried organisms. They are millions of years old and are fossilized under rock and sand. They are efficient energy...

  • Geothermal energy - 501 Words
    Unlike other power plants that rely on coal or other ¬¬¬fossil fuels to create electricity for homes and businesses, geothermal power plants use superheated fluids from the earth’s geothermal energy to generate electricity. When magma heats up the water from underground, it creates superheated fluids. When these super-heated fluids reach the surface they will be turned into steam. This steam will then power a turbine, which will in turn power a conductor. The conductor will then produce...

    Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision). 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....

Three examples of work would be a tractor pulling a float, a mother pushing a baby stroller, and a body builder lift a barbell over their head. Work is measured in joules and the formula for work is Work=Force*Distance. Power is a quantity that measures the rate at which work is...

On the left hand side, the quantity mgh is the force on the ball times its height h above the ground before it was dropped. We call it the gravitational potential energy of the ball before it was dropped. On the right hand side is a quantity (1/2) mv2 which is called the kinetic energy of the ball...

    A release of nuclear energy occurs when the nuclei of atoms are changed. Hydrogen and uranium are two kinds of matter used to produce nuclear energy. In a nuclear reaction, the tremendous binding energy inside a hydrogen or uranium nucleus is released. Nuclear energy is released during atomic fission, when uranium nuclei are split. It is also released during fusion, when hydrogen nuclei combine to form a helium nucleus. In fission and fusion, nuclear energy produces thermal energy, which...
