Conservation of linear momentum in the x-direction gives the following result relating the velocities of the cart and the plate's COM, G: v B = -(m/M) v Gx. From this we know that the cart and G ...

A sphere moving on a smooth horizontal surface (the xy-plane) impacts a set of 13 cubes at rest on the same surface.This impacts leads to a number of subsequent impacts among these cubes. The ...

Optical vortices, which carry orbital angular momentum (OAM), can be flexibly produced and measured with infrared and visible light. Their application is an important research topic for super ...
