Amontons' Laws of Friction
Amontons' Laws of Friction, first explored by Leonardo da Vinci but never published, were rediscovered and first recorded in print during the late 17th century.
There 3 laws of friction are:
- 1. The force of friction is directly proportional to the applied load. (Amontons 1st Law)
- 2. The force of friction is independent of the apparent area of contact. (Amontons 2nd Law)
- 3. Kinetic friction is independent of the sliding velocity. (Coulomb's Law)
NOTE: These 3 laws only apply to dry friction, in which the addition of a lubricant modifies the tribological properties signifiantly.

Famous quotes containing the words laws and/or friction:
“While I am in favor of the Government promptly enforcing the laws for the present, defending the forts and collecting the revenue, I am not in favor of a war policy with a view to the conquest of any of the slave States; except such as are needed to give us a good boundary. If Maryland attempts to go off, suppress her in order to save the Potomac and the District of Columbia. Cut a piece off of western Virginia and keep Missouri and all the Territories.”
—Rutherford Birchard Hayes (1822–1893)
“The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.”
—William Howard Taft (1857–1930)
