Possible to freeze mass in place #1

Closed bryo5363 closed 9 years ago

By generating an extremely high amount of KE, the mass on the pendulum will freeze in place even though it has a sufficiently large velocity vector.

Steps to reproduce -Maximize the length of the string. -Drop the mass from as high as possible -When the mass makes its way to the minimum position, minimize the length of the string. -Enlarge the length. Repeat the process a few times. The mass will hang in place.

After trying to reproduce this issue on OSX 10.9.5 w/ Safari 7.1 and nearly getting sick, I conclude that this issue is no longer present.
