I will take that cartoon to my physics class. I know it will make them either moan or laugh.
Thanks Jerry,

May be a groaner to many, but I’m sure an “I don’t get it” to some of the youth.

Isaac Newton, as the story goes, sat under a tree, and as "something" fell on his head, he declared that he discovered "gravity".
F = ma, or Fw = mg . (where m = mass, and g = the pull of gravity, 9.8 m/sec^2)
Pay attention, quiz tomorrow . :)

In the U.S. we know the pull of gravity as 32 ft/sec^2. The formula also must include the condition "in a vacuum". Otherwise air molecules will slow the rate of acceleration.
