See, when the Three Gorges Dam is full, its local mass and the distance of the mass from Earth’s rotational line increases. This causes what scientists call the moment of inertia to increase ...

Musk clarified that the homework involved the complex topic of deriving moments of inertia from first principles, a concept ...

Elon Musk, a University of Pennsylvania and Wharton School alumnus holds a dual degree in economics and physics.

Photos of Elon Musk’s handwritten college physics homework on rotational dynamics capture the internet’s attention, with Musk ...

Musk recognized the notes and clarified that the work involved deriving “moments of inertia from first principles,” a challenging concept in physics dealing with the rotational properties of objects.

He explained: “For those confused, it’s the derivation of I the mass moment of inertia of a flat square plate. Think F=ma but for rotation. Torque = I * angular acceleration.” Elon Musk's ...
