Talk:Frictionless plane

Image
I removed Image:Free body.gif, as it shows an inclined plane with friction, the opposite of what is being discussed in this article. — M ETS 501 (talk) 19:48, 26 May 2007 (UTC) my techer Mr. Ward has a Frictionless piece of ply wood the we role cars down. —Preceding unsigned comment added by 163.150.53.41 (talk) 19:39, 9 January 2009 (UTC)

Galileo's Two New Sciences
The article has publication date 1608. Should be 1638. That can be checked by looking at the book, Galilei, G.Discorsi e dimostrazioni matematiche intorno á due nuove scienze attinenti alla meccanica & i movimenti locali Appresso gli Elsevirii, 1638. Wikipedia's article on Galileo has the correct date. — Preceding unsigned comment added by Entropier (talk • contribs) 19:41, 29 January 2022 (UTC)
