Purpose: Measuring ‘g’ by dropping steel ball and Ping-Pong ball from the same height and record the time for each dropping. Then, using the equation “h=1/2g*t^2 to calculate ‘g’. For precise, we still need to find ∆g, therefore, the final data about g=gave+∆g. Method: Before we start to do the experiment, we need to find a position which can except the wind and flat ground. After that, two people as a group, one is a golfer, and another is a dropper. First, they measured use tape measure to…
