Transcript
ENERGY Energy can be broken up into 6 types Mechanical Energy Energy an object has because of its motion or position Thermal (or Heat) Energy Energy a substance has based on the movement of its particles Electromagnetic Energy Energy carried by electromagnetic waves (light, x-rays, radio waves, etc.) Electrical Energy Energy produced by the flow of electric charges Chemical Energy Energy stored in chemical bonds Nuclear Energy Energy contained within the nucleus of an atom These types can be broken into 2 Forms Potential Energy: Stored energy an object could potentially have Kinetic Energy: Energy an object has because it is moving Law of Conservation of Energy • Energy cannot be created nor destroyed, but only transferred from one type or system to another Taking a closer look at some of those types of energy… Thermal (or Heat) Energy • Temperature: a measure of how fast the particles are moving in a substance – What is temperature measured in? • Heat: the transfer of thermal energy between substances at different temperatures Energy Transfer • Temperature naturally wants to equalize • Heat will flow from warmer to cooler objects until temperatures are equal Hot Cold 3 Types of Energy Transfer • Conduction: 3 Types of Energy Transfer • Convection: 3 Types of Energy Transfer • Radiation:
