This Chapter 10 summary covers the key concepts of rotational motion and angular momentum in physics. The video explains torque, rotational kinematics, moment of inertia, and conservation of angular ...

If you’ve ever played with tops, you know that some spin easily while others wobble. Ever wonder why? The answer has to do with rotational inertia, a property shared by all rotating systems. Sometimes ...

Let's review a bit of physics in preparation for Part 2 of our technology transfer series on page 28. All elements in a rotating body have a measure of kinetic energy. Simply stated, this is "energy ...

There, I feel better for saying that. So, what is the I term? That is usually called the 'moment of inertia'. Probably a better name would be 'rotational mass'. Just like momentum (regular linear kind ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...

Every dazzling jump on the ice—like Yuzuru Hanyu's quadruple Lutz at the 2017 Grand Prix of Figure Skating in Moscow, Russia—requires a mastery of balance, rotational speed and angular momentum. Aflo ...

Research has shown that rising sea level across the globe has triggered a slowdown in Earth's rotation. A team led by Harvard researcher Jerry Mitrovica published their results in Science Advances ...

Introduction Have you ever wondered why figure skaters are able to spin like a top so quickly? In many cases they're able to increase their speed without pushing off of anything simply by tucking ...
