Continuing with last week's introduction of calculus, Shini leads us through the ways that integrals can help us figure out things like distance when we have several other key bits of information. Say, for instance, you wanted to know how far your window was off the ground. By using integrals, a tennis ball, and a stop watch, you can figure that out! It's all here in this episode of Crash Course Physics!

If you are studying for a high school or college level literature exam, test or quiz, or just looking for a sample practice test to challenge your literary knowledge, take this free literature test and see how well you score.

Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of Rotational Motion!
