How to Succeed at Physics Without Really Trying

Units are your physics superpower! With dimensional analysis, you can get 90% of the way to the answer for many physics problems with next to no work! Get the notes for free here: https://courses.physicswithelliot.com... In any given physics problem, you have a certain list of parameters at your disposal: masses, charges, lengths, and so on, and fundamental constants like G and c. And you're looking for an answer with some particular units. Dimensional analysis is a strategy to figure out how you can combine the given parameters to get the correct units of the answer you want. And often times this approach can get you 90% of the answer with minimal effort. I'll show you how to apply it to three very different problems: the period of a pendulum, the binding energy of a hydrogen atom, and the event horizon radius of a black hole.

About physics help room videos: These are intro-level physics videos aimed at students taking their first physics classes. In each video, I'll teach you the fundamentals of a particular physics topic you're likely to meet in your first classes on mechanics and electromagnetism. About me: I’m Dr. Elliot Schneider. I love physics, and I want to help others learn (and learn to love) physics, too. Whether you’re a beginner just starting out with your physics studies, a more advanced student, or a lifelong learner, I hope you’ll find resources here that enable you to deepen your understanding of the laws of nature.
