Watch the following video tutorial on parabolic paths of action, which are typical for objects flying through the air. When you've finished watching the video, take the quiz.
Parabolic Path of Action Video
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.
