Document Summary
Energy: the potential capacity to move matter. component of an object. Something that the object has for reasons like pe or ke. Potential- in the form of position in a field. Internal (u)- sum of kinetic and potential energy of a system. Conservation of energy: energy may be converted from one form to another but the total quantity doesn"t change. Heat and work: the manner by which energy goes from one object to another system= what"s changing surroundings= where the change is happening, the universe. Heat: energy going in or out of a system because there is a difference in temperature between the system and surroundings. If q is positive +q = heat is entering the system. If q is negative -q = heat is leaving the system (when a reaction occurs in a flask, the flask gets warm) Work (w): energy exchange that results when a force moves an object through a distance.
