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 developd a mental picture of the physical situation. If necessary, sketch a simple diagram of the physical situation to help you visualize it.
- ... identifies the known and unknown quantities and record in an organized manner, often times they can be recorded on the diagram itself; equates given values to the symbols used to represent the corresponding quantity (e.g., v = 3.00x108 m/s, λ = 554 nm, f = ???).
- ... 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.
