Habits of an Effective Problem Solver

An effective problem solver by habit approaches a physics problem in a manner that reflects a collection of disciplined habits. An effective problem-solver...

  • ... reads the problem carefully and develops a mental picture of the physical situation. If necessary, sketches a simple diagram of the physical situation to help you visualize it.
  • ... identifies the known and unknown quantities and records them in an organized manner. Equates given values to the symbols used to represent the corresponding quantity - e.g., ΔV = 9.0 V; R = 0.025 Ω; I = ???.
  • ... uses physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
  • ... identifies the appropriate formula(s) to use.
  • ... performs substitutions and algebraic manipulations in order to solve for the unknown quantity.
