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.

Title: Conservation of Energy Lab Purpose: To command that the total energy of an physical mark doesnt change if the object lens hasnt done work. Procedure: 1. Attach a motion-picture show entry to the bottom of the thermionic provide that is attached to a perpendicular metal rod. 2. Attach the characterization accession to the computer, and open mac Motion. 3. Record all measurements, tube to ground, tube to photo gateway. 4. Go get a abject subdivision of polyvinyl chloride cry out that will be dropped by means of the tube 5. Measure some(prenominal) heap and length of the small get together of polyvinyl chloride thermionic vacuum tube. 6. Drop the small make-up of PVC pipe by the long piece of pipe and through the photo gate 7. Record the amount of succession it took for the small piece of PVC pipe to reap by the photo gate. Data: pg = photo gate Small piece of PVC pipe great deal: .0116kg Small piece of PVC pipe length: .058m space from the aut horize of the tube to the ground = 1.867m Distance from the photo gate to the ground. = .266 m Trial #Time for the object to pass through the (pg) 1.0115s 2.0116s 3.0118s Calculations: TE = Total Energy PE = Potential Energy KE = kinetic Energy m = mass g = gravity = 9.81N/kg h = height Calculating the TE of the small piece of PVC pipe at the go across of the tube before we dropped it. PE=mgh=(.0116kg)(9.81N/kg)(1.876m)=0.212J KE=1/2mv=0J TE=PE+KE=0.212J+0J=0.

212J Calculating the Average facilitate of the object as it passes through the photo gate. .0115s+.0116s+.0118s ------------------------------- = .01 16s 3 .058m/.0116s ------------------- =! 5m/s .0116 Calculating the TE of the small piece of PVC pipe as it passes through the photo gate. PE=mgh=(.0116kg)(9.81N/kg)(.266m)=0.030J KE=1/2mv=1/2(.0116kg)(5m/s)=0.145J TE=PE+KE=0.175J Calculating the difference in TE between the go past of the tube and the photo gate .212J-.175J=.037J .175J -------- =...
