Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

Draw a free body diagram (FBD) of the disk. Step 2: Kinetics (Newton/Euler) Based on your FBD above, write down the linear impulse momentum and angular impulse/momentum equations for the disk. From ...

Segment 4A: Momentum and Impulse We define the terms momentum and impulse. Segment 4A: Momentum and Impulse We define the terms momentum and impulse. We see the impulse-momentum theorem in action by ...

It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...
