Document Summary
Constant acceleration (start from rest) use distance triangle. Constant velocity (same speed all the way through the motion) use distance rectangle. Spacecraft with changing acceleration (not a straight line velocity graph) break down. Galileo"s use of free fall into a lot of little trapezoids. Distance rectangle d = vt exact position. Changing to d = vit (vi is the height of the distance rectangle); use this formula to find. Fancier formula x = vit + at2, where a = acceleration = rise/run. Will be applying this to free fall, an accelerated motion along the y-axis! Galileo chose free fall as the simplest acceleration to study, and used it to model all accelerating systems (ch. Free fall acquiring new increments of speed. galileo than that which repeats itself always in the same manner. galileo. I observe a stone initially at rest falling from an elevated position and continually.
