Lecture Description

This lecture reviews selected concepts previously covered in lectures 6 through 15. Professor Lewin covers work-energy theorem, pendulum energy, simple harmonic oscillators, Newton's Law of Universal Gravitation, resistive forces, and finally collisions and conservation of momentum. At the beginning of class a top is spun on the desk in the lecture hall to show that friction dissipates the top's kinetic energy into heat, and the top quickly falls over. Professor Lewin then spins the same top on a small magic black box and the top does not fall over! At the end of the class the top is still spinning: what's going on?

Course Description

This course is a first-semester freshman physics class in Newtonian Mechanics, Fluid Mechanics, and Kinetic Gas Theory. In addition to the basic concepts a variety of interesting topics are covered in this course: Binary Stars, Neutron Stars, Black Holes, Resonance Phenomena, Musical Instruments, Stellar Collapse, Supernovae, Astronomical observations from very high flying balloons (lecture 35), and you will be allowed a peek into the intriguing Quantum World.
