Title: Conservation of Energy Lab Purpose: To verify that the total energy of an object doesn't change if the object hasn't done work. Procedure: 1. Attach a photo gate to the bottom of the tube that is attached to a vertical metal rod. 2. Attach the photo gate to the computer, and open Mac Motion. 3. Record all measurements, tube to ground, tube to photo gate. 4. Go get a small piece of PVC pipe that will be dropped …showed first 75 words of 481 total…

…showed last 75 words of 481 total…small piece of PVC pipe and the inner wall of the large pipe, as well as the impact of air molecules on the small piece of PVC pipe. Sources of error for this experiment mostly come in the form of setup; if our large PVC pipe was at a small angle it would have increased friction and decreased the total energy of the small piece of PVC pipe as it passed through the photo gate.
