Work Done By A Force
Work Done By A Constant Force
Technically speaking, this video is a tad on the introductory side for Calculus, since it doesn't use any integrals. But that's kind of the point! Work is a confusing topic -- it's basically physics thrown into the middle of a math class -- so it's best if you learn how to do these more basic work problems first, before throwing crazy integrals into the mix.
What the heck is work?
This video is a bookend for the first one. Only this one is even better because it doesn't have numbers! Don't let that fool you, though, this video helps you figure out some of the peculiar vocabulary of work problems. Classic questions will be answered, such as "How can work be negative," and "what the heck is the difference between doing work and getting worked on, and why did I lose five points over it?"
Work Done By A Variable Force (integrals)
This is what you've been waiting for: work problems with integrals. Work is a confusing topic, though, so it's highly recommended that you watch the prior two videos first. Examples: launching satellites, expanding gasses, springs, reeling up chains.
