Transcript
Energy Notes Energy - Ability to do work or cause change. Mechanical Energy - Energy an object has because of its motion or position. Potential Energy - Energy an object has because of its postion or shape. Kinetic Energy - Energy an object has because it is moving. Heat Energy - The energy related to the temperature of a substance. Chemical Energy - Energy stored in chemical bonds. Electromagnetic Energy - Energy which can travel through empty space as well as through matter. Includes visible light, radio waves, X-rays, and others. Nuclear Energy - Energy contained in the nuclei of atoms. Wave - An oscillation that travels from one place to another with a certain velocity. Heat Transfer - Energy will move from an object with a higher temperature to an area object of lower temperature until the temperatures of the objects are equal. Radiation - Transfer of energy through empty space. Conduction - Transfer of heat from a warmer substance to a cooler substance through direct contact. Convection - Transfer of heat in a fluid through currents. Conductor - A substance that conducts energy well. Insulator - Does not conduct energy well. Temperature - The measure of the average kinetic energy of the particles in a substance. Specific Heat - The amount of heat necessary to raise the temperature of 1 kg of a substance 1 degree Celsius. Electricity - The interaction of electric charges. (+) or (-) - Like charges repel; Unlike charges attract. Induction - The process of making an object electric or magnetic which is not normally electric or magnetic by placing them in an electric or magnetic field. Law of Conservation of Energy - Energy cannot be created or destroyed, it can only change forms.
