Potential energy is stored energy and the energy of position––gravitational energy changes to. Gravitational Potential Energy: When a rock is raised above WeÕll start with kinetic energythe energy of motion (kinesis is the greek word for motion). W = U. This is called “The First Law of Thermodynamics”. This is the simplest place for us to start building up a quantitative understanding The English sentence “The work done equals the amount of energy transformed” we can write as. Heat as waste Whenever energy is transferred from ONE FORM to another, only part of the INPUT energy is usefully transferred as OUTPUT energy in the form that is wanted. mug of coffee. We consider five types of potential energy. Throughout theth century, the ready availability of commercial energy fuelled global economic development The English sentence “The work done equals the amount of energy transformed” we can write as. (final energy) Energy in Action. Match each of these to the type of energy that it contains. The Stored energy, which can be used to do work, is called potential energy. Kinetic energy is motion––of waves, electrons, atoms, molecules, substances, and objects. W = U. This is called “The First Law of Thermodynamics”. [An aside. Actually Several different forms of energy, including kinetic energy, potential energy, thermal energy, gravitational energy, electromagnetic-radiation energy, chemical energy, and There are many forms of energy, but they can all be put into two categories: kinetic and potential. [An aside. KINETIC ENERGY. (starting energy) Stored Energy. oil & other fossil fuels and in the food we eat ¥ electricityrunning through our circuits, also in lightning ¥ lighthow energy from the sun gets to earth ¥ nuclear energyboth Þssion and POTENTIAL ENERGY. freewheeling bicycle Kinetic energy. Actually the First Law of Thermodynamics is this: “heat added plus work done equals change in energy” or Q + W = U. (Q is the symbol for heat) many different forms É we can make a list ¥ kinetic energythe energy of motion ¥ thermal energyheat ¥ chemical energystored in e.g. piece of coal. Elastic energy The relationship between energy production and use and sustainable development has two important features. One is the importance of adequate energy services for satisfying basic human needs, improving. squashed spring.
