Document Summary

Step back and look at the whole picture. Study for 2 hours per every hour of class. Repetition is key: take 3-5 short study sessions per day. Look at textbook for specific section or topic. Memorize things dr. zhang specifically mentions to memorize. Law of conservation > or change in potential energy+change in kinetic energy+change in internal energy=0. People study how to take advantage of chemical bonds and the breaking of chemical bonds. Energy: work(w)= force and distance (need both) W= force x distance (if either are 0, the value would be 0, so both are needed) =kg x meters/ second x mass= kg m 2 x s -2 =joules. Heat (q)= energy absorbed or released in a chemical reaction ii. Potential energy (pe): position of an object. Kinetic energy (ke): speed of an object > temperature= average kinetic energy. Internal energy (e): the rest of the energy. Examples: of a particle of moving through space.
