Let's review a bit of physics in preparation for Part 2 of our technology transfer series on page 28. All elements in a rotating body have a measure of kinetic energy. Simply stated, this is "energy ...

If you’ve ever played with tops, you know that some spin easily while others wobble. Ever wonder why? The answer has to do with rotational inertia, a property shared by all rotating systems. Sometimes ...

(Phys.org)—Newton's gravitational constant, G, has been measured about a dozen times over the last 40 years, but the results have varied by much more than would be expected due to random and ...
