PSA Microgravity Challenge
Bullyard State School
Mr. Brennan's 6/7th Grade - Zac
This is the design of the year 6/7 class of Bullyard
State School that they think is a workable plan. There are 5 hooks
which will control the 3 basic motions that it will have to be completed.
The system is controlled by string being tightened and loosened to
vary its position.
Response from Expert Dan Andrews:
How does this work for sideways and up/down
If I'm understanding it correctly, if I were
to push on it sideways, the ball would move and then swing right back
(like a wrecking ball). If I were to push up on the ball, and remove my
finger, the ball would fall back down.
Try thinking of a way that if a pushed on the
ball, and then removed my finger, the ball would keep moving, just as
it would in microgravity...
