Newton's Theory of Universal Gravitation

Need I explain? I spent the better half of Saturday in the Emergency Room after my husband fell off of the very TOP (yes, I do mean the tippy-top) of a 6 foot ladder! Lucky for him, the mass of his A$$ is greater than that of his head! Meaning, he has a broken tail-bone and his back is kicking up a fuss. I loaded him up on muscle relaxers and pain meds today so I wouldn’t have to listen to the moaning. I did ask him this morning if he would clean the roof for me. I even volunteered to hold the ladder and hand him the hose, but I couldn’t get him off the couch. 😦

Modern work on gravitational theory began with the work of Galileo Galilei in the late 16th and early 17th centuries. In his famous (though possibly apocryphal[1]) experiment dropping balls from the Tower of Pisa, and later with careful measurements of balls rolling down inclines, Galileo showed that gravitation accelerates all objects at the same rate. This was a major departure from Aristotle‘s belief that heavier objects accelerate faster.[2] Galileo correctly postulated air resistance as the reason that lighter objects may fall more slowly in an atmosphere. Galileo’s work set the stage for the formulation of Newton’s theory of gravity. (My thanks to Wikipedia)
