Discover how to derive the orbital angular velocity of a hydrogen atom step by step using classical and quantum physics principles. This video breaks down the math behind electron motion, angular ...

I love using seemingly random data to figure out stuff I wouldn't otherwise know. You can do this with all kinds of things, but in this example, I use video that I recorded from an airplane to figure ...

Ask any engineer what the velocity of a point on a rigidbody is, and he will correctly say that it is the timerate of change of a linear position vector. Ask anyengineer what angular velocity is, and ...
