Tentative schedule and reading assignments
Please watch complimentary video about resistive forces, i.e. drag and effects of viscosity. Even though in the lecture the motion of the spheres is discussed. You can think about pipes as “inverted” spheres, than you would see the connection to discussion of viscose flow in Ch14.7 of the text book. This is, by the way, your reading assignment.
By the way, I strongly recommend other lectures by Dr. Lewin.
Building examples:
Building mistake: Hyatt Regency walkway collapse
Michael Jackson gravity defying move
hit the professor demo
rocket sled demo
light ball bouncing from the heavy ball demo
The Big Bang Theory, inclined plane why 1/2 less force needed?
Projectile motion
Imagine a rocket which adjusted its trust in such a way that it is hoovering still above the Earth surface, i.e. it is neither going up nor down nor sideways.
Clearly the energy is constantly used since the rocket burns the fuel to maintain above setting. But there is apparently no change of kinetic and potential energy.
Explain this strange paradox. The explanation should not contradict the things which we learned in the class.
Hint: think outside of the box.
