Summary:

• When gravity is the only significant force the path of action is a parabolic arc.
• For a parabolic path of action the horizontal spacings are constant and uniform.
• The vertical spacings are the same as for simple falling motion (i.e., The Odd Rule, Fourth Down at Half-time).
• Two common errors are: Making the arc too straight; Not having the apex centered.
• Path of action can have the right shape but the timing and spacing can still be wrong.
