One ball is dropped freely, while the other hangs from a string, acting as a simple pendulum. Using two photogates, we see that the vertical velocity of the dropped ball is identical to the horizontal velocity of the pendulum, measured at the same height. Potential energy has been converted to kinetic energy equally in both cases. 72 tag:techtv.mit.edu,:Array/218003940 2008-12-19 12:33:18 -0500 music MUSIC Session 4 2171 tag:techtv.mit.edu,:Array/217981600 2009-02-24 15:29:41 -0500 Blended Learning Open Source Science or Math Studies (BLOSSOMS) BLOSSOMS-Taking Walks, Delivering Mail: An Introduction to Graph Theory with Karima Nigmatulina 3326 tag:techtv.mit.edu,:Array/217959500 2009-07-02 17:10:44 -0400 RLE Professor Muriel Medard of MIT discusses research and education in her group, and the intellectual challenges facing engineers at the frontiers of communications, networks, and coding. 306 tag:techtv.mit.edu,:Array/217937640 2009-08-17 13:48:58 -0400 MIT OpenCourseWare This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. 2709 tag:techtv.mit.edu,:Array/217913380 2009-11-05 15:39:04 -0500 Blended Learning Open Source Science or Math Studies (BLOSSOMS) The main objective of this lesson is to motivate students’ thoughts and get them excited about some probability concepts. The aim is to present probability theory in as simple a manner as possible. It is hoped that students will learn that probability theory is a basic tool for handling an uncertain future and making a decision. 2084
