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 ...

Let me get rid of the θ and r3 terms where: This gives an angular momentum of: The same as before. So, although the person is moving in a straight line the angular momentum (about that rotation point) ...

Talk about making the world go round. Earth’s rotational speed is changing, and we’re more than partly responsible. A gigantic dam, our extraction of groundwater, melting ice sheets and rising sea ...
