PHY 158 Lecture Notes - Lecture 2: Lab Report, Kinematics
Document Summary
V1(1) in this experiment we tested equations of kinematics that describe free fall and measured the acceleration due to gravity. We did this by dropping a nylon ball and a steel ball of different masses from rest at six different heights five times each. To calculate the time of free fall accurately, we used a drop box with a magnet and a flight pad. Nylon ball y vs. t2 f(x) = 480. 22x - 0. 02. Steel ball y vs. t2 f(x) = 488. 66x - 0. 32. Calculating g and g. s = 488. 6584 s = 1. 038896 y= g t2. Report of g g for nylon ball. Report of g g for steel ball. Least decimal of answer is same power of 10 as uncertainty. The accepted value, g = 980 cm/s2, is almost within the range of my calculated g g for both the nylon and steel balls.
