Impetus may refer to:
The theory of impetus was an auxiliary or secondary theory of Aristotelian dynamics, put forth initially to explain projectile motion against gravity. It was introduced by John Philoponus in the 6th century and elaborated by Nur ad-Din al-Bitruji at the end of the 12th century, but was only established in western scientific thought by Jean Buridan in the 14th century. It is the intellectual precursor to the concepts of inertia, momentum and acceleration in classical mechanics.
In the 6th century, John Philoponus partly accepted Aristotle's theory that "continuation of motion depends on continued action of a force," but modified it to include his idea that the hurled body acquires a motive power or inclination for forced movement from the agent producing the initial motion and that this power secures the continuation of such motion. However, he argued that this impressed virtue was temporary; that it was a self-expending inclination, and thus the violent motion produced comes to an end, changing back into natural motion.
The impetus is a ballroom dance step used in the Waltz, FoxTrot or Quickstep. The open impetus is one of several ways to get into promenade position and is used to turn dancers around corners or change their direction on the dance floor. It is often performed after a natural turn.
The open impetus has less turn than the closed impetus. The closed impetus remains in closed position, while the open impetus ends in an open promenade position.
The open impetus is a Silver syllabus variation on the closed impetus.

Indian or Indians may refer to:
Indian is an American brand of motorcycles originally produced from 1901 to 1953 in Springfield, Massachusetts, United States. Hendee Manufacturing Company initially produced the motorcycles, but the name was changed to The Indian Motocycle Manufacturing Company [sic] in 1928.
The Indian factory team took the first three places in the 1911 Isle of Man Tourist Trophy. During the 1910s, Indian became the largest manufacturer of motorcycles in the world. Indian's most popular models were the Scout, made from 1920 to 1946, and the Chief, made from 1922 to 1953.
The Indian Motocycle Manufacturing Company went bankrupt in 1953. Various organizations tried to perpetuate the Indian Brand name in subsequent years, with limited success. In 2011, Polaris Industries purchased Indian Motorcycles and moved operations from North Carolina and merged them into their existing facilities in Minnesota and Iowa. Since August 2013, Polaris have marketed three modern Indian motorcycles that reflect Indian's traditional styling.
Indian is the soundtrack to the 1996 Tamil film of the same name, directed by S. Shankar and starring Kamal Hassan. The soundtrack album includes five tracks composed by A. R. Rahman and was released on 1996 by Pyramid. The soundtrack was highly popular upon release and was also released in Hindi as Hindustani by TIPS and in Telugu as Bharateeyudu by T-Series. The lyrics were written by Vaali and Vairamuthu for the original version, P. K. Mishra for Hindustani and Bhuvanachandra for Bharateeyudu.
The soundtrack proved extremely successful and sold about 6 lakhs records within a few days of release.
