Elasticity and Young's Modulus. The fractional length deformation of a material (the strain) depends on the force per unit area (the stress). The stress vs. strain dependence is described con...
435 viewsThis lecture reviews selected topics previously covered in lectures 1 through 5. This lecture is part of 8.01 Physics I: Classical Mechanics, as taught in Fall 1999 by Dr. Walter Lewin at MIT. This ...
316 viewsThis lecture covers resistive forces such as air drag. It includes the viscous (linear in velocity) and pressure (quadratic in velocity) terms. Quantitative demonstrations with balloons and with ball ...
245 viewsThis lecture deals exclusively with frictional forces. This lecture is part of 8.01 Physics I: Classical Mechanics, as taught in Fall 1999 by Dr. Walter Lewin at MIT. This video was formerly hosted ...
266 viewsConcepts 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). Us...
245 viewsThe concepts introduced are: work, conservative forces, potential energy, kinetic energy, mechanical energy, and Newton's law of universal gravitation. This lecture is part of 8.01 Physics I...
341 viewsThis lecture is all about motion of projectiles (if air drag can be ignored). The objects experience a constant vertical acceleration due to the acceleration of gravity (see also Lecture 12). This le...
350 viewsThis lecture is all about Newton's First (inertia), Second (F=ma) and Third (action=-reaction) Laws. This lecture is part of 8.01 Physics I: Classical Mechanics, as taught in Fall 1999 by Dr...
200 viewsThis lecture is about uniform circular motion. There is a constant radial acceleration (centripetal acceleration) but constant tangential speed. This lecture is part of 8.01 Physics I: Classical Mech...
206 viewsThis lecture is about vectors and how to add, subtract, decompose and multiply vectors. Decomposing vectors in 2 (or 3) dimensions is a key concept that will be used throughout the course. This lectu...
214 viewsThis lecture is an introduction to kinematics which ultimately leads (in Lecture 4) to trajectories in 3 dimensions. This lecture is part of 8.01 Physics I: Classical Mechanics, as taught in Fall 199...
203 viewsThis lecture is about units, dimensions, measurements and associated uncertainties, dimensional analysis, and scaling arguments. This lecture is part of 8.01 Physics I: Classical Mechanics, as taught...
