QUESTIONS: 1. Why should the graph of velocity versus time for a falling plummet be a straight line? It should be a straight line because acceleration (the slope of the velocity versus time graph) is constant (about 980.23 cm/s 2 in Schnecksville, PA). Why should the graph of total distance traveled versus time for a falling plummet not be a straight line? The velocity (slope of the distance traveled versus time graph) is not constant (it’s accelerating), and in order to have a straight line, the slope needs to be constant. 2. During any particular time interval of 1/60 th of a second, was the velocity constant? Yes, velocity had no noticeable change during the interval of 5/60 th of a second to 6/60 th of a second. This can most likely be attributed to error in the measuring devices. Theoretically there should be no interval with consistent velocity in a freefall experiment due to gravitational acceleration. When was the instantaneous velocity greater: at the beginning of the 1/60
