A long time ago a formula was devised for calculating kinetic energy, the energy needed to move a body from one place to another. This energy (E) was dependent on both the mass (M) of the body and the ...

In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own ...

You know about Newton's Cradle. Either you have seen it as an office desk toy, or as a physics demo. It goes: click, click, click, click. So let me show you how it works. What better way to show this ...

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 ...

When an electron is ejected from a metal surface it has kinetic energy. The amount of kinetic energy the electron has depends on the difference between the energy of the photon and the work function ...
