Impetus
From Free net encyclopedia
Impetus has several possible meanings:
- In the history of science, impetus is an obsolete scientific theory of motion, largely developed by Jean Buridan in the 14th century. It was superseded by the modern theory of inertia developed by Galileo Galilei.
- See main article: Inertia: History.
- In music theory, and specifically, piano theory, Impetus can mean double dotting a dotted note; for example if one double dots a crotchet, then instead of playing a quaver one plays a semiquaver which gives the music movement with sudden kick. Double dotting a note is usually also accompanied by getting louder with a crescendo.de:Impetus
