I'm working on a lab experiment using https://phet.colorado.edu/en/simulation/the-ramp the ramp. Using a piano with the ramp angle set to 10 degrees, I'm supposed to test the work-energy theorem by letting the piano roll down the slope with no friction and record the values of work and energy. Based on what I know, I thought under these circumstances, the total mechanical energy of the piano should remain the same as it slides down. It would just convert from potential energy to kinetic energy; however, this is not the observed case and I can't explain why. Uploaded is the spreadsheet where I recorded my results.
