Chapter 2: Problem Solving Suggestions
¢ Read the problem carefully so that you can identify what is given, what the contstraints are, and what must be solved for
¢ Draw a sketch of the problem - Specify the frame of reference (axes) and positive direction
¢ Identify known quantities
¢ For problems involving motion with constant acceleration, use the kinematic equations with constant acceleration.
¢ For problems involving free fall motion, the kinematic equations with constant acceleration can be used.
Ø Select the origin so that the problem is simplified.
Ø Select a positive direction and stick with it (be consistent throughout the problem)
Ø Be careful with the sign of g - it depends upon the positive direction chosen
Ø In some cases you have 1 too many variables in an equation - consider solving another expression for the value of one of the variables first
