When you swing a ball on a rope in a circle above your head, what keeps it moving in that circular path? This applies to any object moving in a circle, not just a ball on a rope - the force and ...

We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...

Vertical circular motion is a special type of circular motion in which the forces acting on an object change as it moves along a vertical loop. Specifically, the normal force varies throughout the ...

Abstract: It is a challenging and attractive topic to extend the aperture dimension of linear arrays with convenient configuration for two-dimensional (2D) direction of arrival (DOA) estimation. In ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
