Video for AP Physics 1 demonstrating visual conceptualization of energy exchange between kinetic and potential energy.
Score: 52Aidan Rowan says: This was a really good video, and I did burst out laughing when you introduced "Buckets". Sometimes the camera was a bit shaky, and you probably could have done without writing the question at the beginning of the video down on a piece of paper. Something that does confuse me slightly is that when the ball hits the ground, some of the kinetic energy would have gone out of the system, into the ground. If you could have explained that a bit more, that would have been good.
Hubbell says: Would be nice if you compared the velocity at State 2 to the velocity at State 3 and showed that it is going more than half as fast as it will be be when it hits the ground. I do like the buckets a lot.
