Lecture Description
This lecture is about vectors and how to add, subtract, decompose and multiply vectors. Decomposing vectors in two (or three) dimensions is a key concept that will be used throughout the course. Professor Lewin throws an object up, and decomposes its initial velocity into a horizontal and a vertical direction.
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.
