PHY 158 Lecture Notes - Lecture 3: Protractor, Launch Track, Lab Report
Document Summary
Vi(1) in this experiment we studied the parabolic path of a particle moving in two dimensions under the influence of a constant acceleration due to gravity. A ball was launched from a ramp, leaving the ramp at an angle = 30 . The change in y from the launch point is given by h and the change in x from the launch point is given by d. Vi(2) i then made a table of h/d vs. d using the average values of h/d for each length d. next, i graphed the data. 0. 704 h/d vs. d f(x) = 0. 02x - 0. 71. Vi(3) using linest in excel, i determined the slope, s, intercept, b, and the uncertainties in both of these quantities, s and b. s = 0. 0219 s = 0. 000499 b = -0. 705 b = 0. 0244. The average of as measured with the protractor on the launch track is m.
