.... an object fell to the earth at a rate of about 9.8 meters (32 feet) per second second as pointed out by Galileo. Thus "the apple that fell from the tree" fell to Earth at about this rate.

Therefore when the apple fell it went straight towards the center of the earth (accelerating at about 9.8 meters per second second). Newton then figured that the same force that pulled the apple to Earth al ....
