Concepts covered in this lecture begin with the restoring force of a spring (Hooke's Law) which leads to an equation of motion that is characteristic of a simple harmonic oscillator (SHO). Using the small angle approximation, a similar expression is reached for a pendulum. To demonstrate that the period is independent of the mass of the bob, Professor Lewin places himself at the end of the 5 meter long cable and measures the period.
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.
The Massachusetts Institute of Technology (MIT), founded in 1861, is located in Cambridge, Massachusetts, and is one of the foremost U.S. institutions in science and technology. It is comprised of five schools and one college, including the renowned School of Engineering and Sloan School of Management, offering Bachelor's, Master's, and Doctorate degrees. Notable alumni include Ben Bernanke, Chairman of the Federal Reserve, Benjamin Netanyahu, prime minister of Israel, and American astronaut "Buzz" Aldrin.
