It was about this moment when gravity, taken aback as much as anyone else by the goings on, noticed Petty high up in the air and decided it was about time it reasserted itself on matters.

The old physics teacher in me twinkles with delight. I see now that my explanation of the way things worked was dry and unintuitive; small wonder students have difficulty with the stuff. Newton was a cad.

Some wit in my first physics class asked the teacher whether perhaps it was that the ball thrown straight up in the air lingered there for a moment because it was building up energy to go back down again. Laughing

I think it lingers because it's afraid to go back down.
