I agree with Dr. Vandiver up to a point. The kinetic vibration from a K1 and K2 facilitated solution has to be met with proper centrifugal force applied properly. I am excited with the new development of Euler's Formula to prove true kinetic energy displacement. MIT has allowed me to broaden Euler's Formula and has allowed me to truly invent the way kinetic motion through displacement exists. This will actually be covered in my theses. 7.5 years at MIT and I am finally starting to visualize the light at the end of the tunnel.

I think it's because xs is the displacement of the block in the static condition, meaning it's not dependent on time. This makes it a constant. Left and right side of the equation are equal meaning they can both be subtracted out of the equation.

The main reason is money. MIT contributes 1M+ every year to MIT OpenCourseWare. Even with that funding, we are only able to record a limited number of full courses each year (~12 courses). We try and prioritize which courses we can publish by a number of factors. Unfortunately, 2.004 has not made the video lists. Maybe sometime in the future we will get funding and time to recording 2.004. We do have materials for 2.004, just not videos: ocw.mit.edu/courses/mechanical-engineering/2-004-dynamics-and-control-ii-spring-2008/. Best wishes on your studies!
