Angular Motion and Torque

More spinning things! Records, and wheels, and doors, and other fun things. The equations that govern this kind of motion are just like the ones we learned in kinematics, except they have different symbols. Lots of funky Greek letters in this one, folks. Watch the whole Classical Physics playlist: Modern Physics Tutorials: Mathematics Tutorials: General […]

Rotational Inertia

097 – Rotational Inertia In this video Paul Andersen explains how the angular momentum of an object if a product of the rotational inertia and the angular velocity. The rotational inertia depends on the mass, radius and shape of the rotating objects. A sample calculation and several examples are included. Do you speak another language? […]

What If The Earth Stopped Spinning?

Hey, Vsauce. Michael here. The Earth is spinning and we are spinning along with it. But what if the Earth suddenly stopped spinning? Well, first of all, you would gain weight. But that would be the least of your worries. The spin of our planet is important and literally giving you the time of your […]
