Document Summary
Transfer of energy arrows: down arrow= release energy, up arrow= add energy. Work: exertion of a force through a distance o. D: distance: energy required to move an object through a given distance, energy put in to do something, ie. linemen moving sled. Work= force (exerted on sled) x distance (how far the sled is pushed) Heat: flow of energy from one object to another: energy flows from warm object to cooler one. Thermal energy: portion of objects total energy that rises as temperature increases. Chemical reactions: one or more substance combine into different substances: energy production: lose energy or harness energy for work. Potential energy: stored energy: what could be used in the future. U: speed: between two objects going the same speed but with different masses, the heavier one has the more kinetic energy. Pure water: cant be separated into simpler forms of matter. Physical process: transformation of a sample of matter: ie.
