All matter moves through space-time at the universal constant— the speed of light— but this speed is shared between motion in space and the flow of time. Objects don’t speed up beyond light speed; ...

Consider the mechanism shown below, where link AB is rotating in the counter clockwise sense with a constant angular speed of ω AB. An animation of this motion is shown below. Plots for the angular ...

When you (or whoever) steps off the merry go round, you still have angular momentum even though you are not moving in a circle. Really. If you are moving in a straight line, you could think of ...
