"A fake force is one of those forces that introductory texts tell you arenât real - like centrifugal force. They arenât real in the sense that they are due to one of the fundamental interactions. Basically, introductory texts (and even blogs like this one - not a bad summary of real vs. fake forces) attack the centrifugal force. This is because it is so common for students to want to use these faux forces in the wrong way. Better to just not use them at all.

Anyway, there are times when faux forces are awesome. Just to be clear, a faux force is needed to use normal newtonian mechanics when the reference frame is accelerating. To show this, let me look at the following problem. I will solve it without and then with fake forces."

"Called Mars-500, the Russian-led project based at the Institute for Biomedical Problems here will culminate in a 520-day simulation beginning early next year of a complete manned mission to the planet â a time frame that incorporates launching to Mars touchdown and back â that scientists hope will edge humanity a little closer to that next giant leap."

"In the spirit of this age of economic restructuring, I will simply declare how often people may blog. Most of you should average four to six posts a day. If youâre a group blog, you may post once an hour. "
