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 ...

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 ...

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 ...

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 ...
