Potential and Kinetic Energy Lab

We set up a ramp to send a car down. We measured potential energy at the start of the exeriment. Then after sending the car down the ramp we measured the kinetic energy as well.

Mass of car: 35.1 g or .0351 Weight of car: .351 N Height of ramp: .06 M Potential energy of car: PE= W x H PE= .351 x .06 PE= .02106 J Distance of ramp: .925 M Time it took to get down ramp: Trial 1: 1.94 Trial 2: 1.62 Trial 3: 1.78 Average time: 1.78 Velocity: V=d/t V= .925/1.78 V= .5196629 Final Velocity= fV= Va x 2 fV= .5196629 x 2 fV= 1.0393258 Kinetic Energy= KE=mv2/2 KE=.0351(1.0393258)2/2 KE=.0351(1.08019811)/2 KE= .01895747 Summary: The kinetic energy was less than the potential energy at the end of the lab. This happened because some energy was converted into sound and thermal energy as well as potential energy.

This is our lab!
