Free Fall Objective: To measure the acceleration of gravity using a tape timer Materials / Apparatus: Tape Timer Support Rods Ruler Stop Watch DC power supply Mass Piece Procedure: We started by calibrating the tape timer. We do this so that we know how long it takes for the hammer to strike down each time. We did this by starting the tape timer and pulling a sample piece of tape through it while someone timed how …showed first 75 words of 727 total…

I found that our average velocity for the mass was 164.32 cm/s and our results for average acceleration of gravity was 440.3 cm/s/s. ssI feel that this method isn’t too accurate due friction, and the hammer striking the tape every .019 seconds for us, which causes the tape to slow down every .019 seconds. However it did help me get an understanding of free fall, and acceleration of gravity.
