 Problem solving [I SEE]I = IdentifyS= Set upE = ExecuteE = Evaluate Target Variable The quantity whose value you're trying to find. Identify Find out what is relivant, find target variable. Set Up The problem: figure out what tools to use (ie:equations), how to use them possably draw a sketch. Execute The solution: "do the math". List equations and variables, then solve the variables. Evaluate Your answer: does your answer make sence? Model A simplified version of a physical system that would be too complicated to analyze in full detail. Physical Quantity Any number that is used to describe a physical phenomenon quantitatively. Operational definition Defined by how we use them. 1 Kilometer = 1Km = 103 meters = 103 m 1 Sec Is the amount of time required for 9,192,631,770 cycles of this microwave radiation. Meter The distance that light traveles in a vacume in 1 / 299,792,458 secound.
