Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We’ll start by looking at motion itself. Then, we’ll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you’ll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

This geometry video tutorial provides a basic introduction into how to use the distance formula to calculate the distance between two points. It also explains how to solve word problems such as how to calculate the area of a circle given the coordinates of the center and a point on the circle using the distance…

Reviewing big ideas of polar coordinates for the AP Calculus BC exam. Here’s a pdf summary of the slides: https://goo.gl/5JbQaK We go over converting to rectangular; finding a bunch of derivatives; finding area; and related rates. Also I give a list of the most recent polar FRQs. See my other videos for lots more on…
