Unformatted text preview: Physics 1A Lecture 3A "Mathematics is the door and the key to the sciences.-- Roger Bacon Falling Bodies Galileo was the frst to predict that alling bodies on Earth would all with a distance proportional to time squared (D t 2 ). Galileo surmised through repeated experiment tha at a given location on the Earth and in the absence o air resistance, all objects all with the same uniorm acceleration. Galileo elt that earlier work neglected the eec that air riction (i.e. resistance) had on dierent objects. The uniorm acceleration Galileo talked about was the acceleration due to gravity, g. Falling Bodies In SI units, g is generally regarded as being 9.80m/s 2 . g varies slightly depending on where you are on Earth, but it always points downward towards the Earth. Falling Bodies Example In the original Superman comics, Superman was unable to fy but could simply leap tall buildings in a single bound. Supermans range was about one eighth o a mile (201m)....
