Breaking things in the name of science!

Chandler Floyd says: I think this video is a really good example of experimentation. When I think of breaking objects, I usually think of the necessary energy output indirectly, either through what item do I need to use or how fast do I need to throw that item. Kinetic energy combines the two, and I thought this video did a good job explaining that. Also, I enjoyed the use of analyzing data you collected rather than making up fake numbers to use.

Jeremy Seloff says: I thought this was an awesome video. It was a great way of explaining kinetic energy in an unorthodox sort of way; it was much more captivating than just doing a simple problem solving for KE. The fact that you set up an experiment which not only proved the formula almost exactly but also explained the topic is very impressive and worth watching.

Michael Becker says: This video does a great job of using experimentation to explain both the idea of Kinetic Energy and the relationship between mass and velocity to Kinetic energy through the precise measurements made in the experiment and with the help of Excel. Connor clearly put a lot of time into this video, and it paid off. The video is both informative and fun to watch from the experimentation to the funny pictures as he talks over the information.

Benjamin Liske says: I am extremely pleased with the quality of this video: both scientificly accurate and engaging. I am also astonished by the efficiency with which this experiment was designed and implemented.

Mitchell Coverstone says: Very intellectually constructed experiment and well put together video. I loved the part where he loaded up the firing device and then pressed the trigger that made the bullet go and waited a couple seconds after the dart had been shot to say fire. This is a great way to look at KE by measuring the KE using the number of sheets of paper. I probably wouldn't have ever thought of something that clever.

Olivia Bishop says: I really liked this video in its entirety. The explanations were clear and creative, and it held my attention from start to finish. The experimentation helped the explanation of Kinetic Energy, especially on a detailed level with Excel. Collecting specific data rather than designing a hypothetical scenario was engaging and well done.
