One of my colleagues is doing a pendulum study in her 5th grade classroom. I thought it would be interesting to do a Squeak project about pendulums. This is as far as I've gotten...I'm not sure how to make the pendulum swing while it's fixed point stays attached to the blue block. Any suggestions? Phil
Wonderful, I've got the thing swinging from a fixed point, but it's not a pendulum yet...it keeps swinging at the same rate and returns to the same position. Anyone want to venture a hint as to how to slow it down relative to the length of its "string?" Phil

Hi Phil,
The easiest way of doing this is to draw a sketch for the pendulum and then set both the "center of rotation" and its "heading arrow" accordingly:

What might be useful to all the mentors/educators on this list is if Alan or someone could recommend a book or resource reviewing "All the Real Math To Which School (Including College) Refused You Access."
Does such a thing exist?
Best,
John
