Since the plate does not bounce back, vGx = 0. And from the above result for conservation of linear momentum, we see that vB = 0. In other words, the system comes to an abrupt stop. You can see this ...

Now I can write the angular momentum principle: Now back to linear momentum. Suppose that I am riding on a friction free train car that is moving at some constant velocity (without an engine).

The fact that light carries both linear and angular momentum is well-known to physicists. One application of the linear momentum of light is for optical tweezers, in which the refraction of a ...
