the. Marble traveled. With the average distance and time (calculated using the time equation given on the lab), the horizontal velocity and subsequent kinetic energy was calculated. Results The results of the experimental procedure provided the data necessary to calculate the kinetic and potential energy for the experiment, 0.00325J and 0.00756J respectively. These
4 DETERMINATION OF THE LAW OF CONSERVATION OF ENERGY 1 values allow for further analysis in the calculations and discussion. (The remaining raw and calculated data can be found after the analysis). Time elapsed: t = 2 h 2 g 0.4351 seconds = 2 × 0.9275 9.8 Horizontal Velocity: v = d t 0.4821 m 0.4351 sec = 1. 1080 m/s Kinetic energy is therefore: KE = 1 2 m v 2 1 2 .053 × 1.1080 2 = 0.00325 J Potential energy: PE = mgh 0.00756 J = 0.053 × 9.8 × 0.9275 Mechanical energy is then: ME = PE + KE 0.00756 + 0.00325 = 0.01081 J Percent Error:

The law of conservation of energy states that energy is not lost, but only transferred into another form. In this experiment, the kinetic energy

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
