Pendulums tick faster when they weigh more. ie a falling pendulum in any gravity won't tick as it is effectively weightless.. I was wondering if it were possible to make an upside down pendulum? I've imagined that you could have an arm with a weight that is above the pivot point instead of below. To keep it up there you would have the arm extend past the pivot point into the bottom area and have this lower part of the arm attached to the opposite sides of a frame by springs to both sides. Although not as effective and long lasting as a normal pendulum I wonder if this can be done to create an upside down pendulum that ticks for awhile... Now, I then have the question, would this upside down pendulum tick faster when it is on a table in higher relative gravity or would it tick slower for higher relative gravity - opposite to its normal counterpart?
