LEARNING GOAL FOR TODAY: Work on Parachutes

Now let's work on developing a parachute that we can test in class.

  • We will drop all of our parachutes from the skybridge
  • Make sure your parachute is fully deployed when you drop it
  • We will make several calculations:
    • We know the object will fall at 9.8 m/s/s without the parachute
    • We can calculate the actual acceleration of the item with the parachute using the basic physics equation d = 1/2at2
    • From that information we can find the drag/deceleration caused by the parachute

We have two goals:

To develop a parachute that will leave the skybridge and hit the ground at a relatively gentle speed (we'll talk about that).

To hit a target (avoid straying side to side too much)

Work with your group to sketch a parachute to accomplish these tasks (you can use paper, trash bag plastic or any other material you bring from home)

  • Anticipate problems that might arouse after doing your sketch
  • Make changes to your sketch
  • Build your parachute
  • Test
  • Debug
  • Repeat
