What is terminal velocity?
Explain how terminal velocity relates to
Newton’s 3rd Law.
II Design and Test
Your job: Design a parachute that will carry a 50 g mass and fall more slowly than any other using only the materials supplied.
-Two plastic trash bags
-50 g mass
-10 ft of string
(No, you may not have any additional materials)
The winning group (i.e., the group with
the slowest time) will have demonstrated that they have mastered their
understanding of Newton’s 3rd Law better than the others by having the
longest average time.
1st place: Full credit on the performance section toward the overall score
Last place: Lose 10 points
Those in between successively lose points up to the 10 lost in last place.
Sketch the design of your parachute.
Draw a free-body diagram of your parachute
falling through the air. Include and label all appropriate force
List five variables regarding the parachute
that you manipulated (or could have) in the design process. Also,
(where applicable) label these in the diagram above.
In your opinion, which variable(s) turned
out to be the most important in the design of an effective parachute).
(Base your answer on all the parachutes you observed, not merely your own
Describe one design that was rejected and
explain why you rejected it.
