Determination of gravitational acceleration: a) For the three trials with the same LVL, calculate the average velocities and horizontal distances traveled and record them in Table-1. b) Plot Ax versus vo graph and from the slope of the best fit line determine the gravitational acceleration. If we apply Equation 4 to the motion of the steel ball along the y-direction 1 Ay = Voyt - gt with Ay = y - y = -h where, h is the height the ball drops. And note that the initial velocity along the y- direction is zero. Hence: h= zgt t = For the motion along x, we have Equation 3. Ax = Voxt and since Vox = 1, and we determined t above by studying motion along y, Ax is given by, Ax= V |2h 9 2h 9 Hence the slope of Ax vs. 1, should be 2h/g. You can deduce gravitational acceleration from this slope. c) Calculate the percent error in your experiment: Determination of gravitational acceleration: a) For the three trials with the same LVL, calculate the average velocities and horizontal distances traveled and record them in Table-1. b) Plot Ax versus vo graph and from the slope of the best fit line determine the gravitational acceleration.
