Impulse \Im*pulse"\, v. t. [See Impel.] To impel; to incite. [Obs.]
--Pope.

Impulse \Im"pulse\, n. [L. impulsus, fr. impellere. See Impel.]

1. The act of impelling, or driving onward with sudden force; impulsion; especially, force so communicated as to produced motion suddenly, or immediately.

   All spontaneous animal motion is performed by mechanical impulse.
   --S. Clarke.

2. The effect of an impelling force; motion produced by a sudden or momentary force.

3. (Mech.) The action of a force during a very small interval of time; the effect of such action; as, the impulse of a sudden blow upon a hard elastic body.

4. A mental force which simply and directly urges to action; hasty inclination; sudden motive; momentary or transient influence of appetite or passion; propension; incitement; as, a man of good impulses; passion often gives a violent impulse to the will; to buy something on impulse.

   These were my natural impulses for the undertaking.
   --Dryden.

   Syn: Force; incentive; influence; motive; feeling; incitement; instigation.

early 15c., "an act of impelling, a thrust, push," from Latin impulsus "a push against, pressure, shock," also "incitement, instigation, impulse," past participle of impellere (see impel). Meaning "stimulus in the mind arising from some state or feeling" first recorded 1640s.

n. 1 A thrust; a push; a sudden force that impels. 2 A wish or urge, particularly a sudden one prompting action. vb. (context obsolete English) To impel; to incite.

1. n. an instinctive motive; "profound religious impulses" [syn: urge]

2. a sudden desire; "he bought it on an impulse" [syn: caprice, whim]

3. the electrical discharge that travels along a nerve fiber; "they demonstrated the transmission of impulses from the cortex to the hypothalamus" [syn: nerve impulse]

4. (electronics) a sharp transient wave in the normal electrical state (or a series of such transients); "the pulsations seemed to be coming from a star" [syn: pulsation, pulsing, pulse]

5. the act of applying force suddenly; "the impulse knocked him over" [syn: impulsion, impetus]

6. an impelling force or strength; "the car's momentum carried it off the road" [syn: momentum]

In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector in the same direction. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction. The SI unit of impulse is the newton second (N·s), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kg·m/s). The corresponding English engineering units are the pound-second (lbf·s) and the slug-foot per second (slug·ft/s).

A resultant force causes acceleration and a change in the velocity of the body for as long as it acts. A resultant force applied over a longer time therefore produces a bigger change in linear momentum than the same force applied briefly: the change in momentum is equal to the product of the average force and duration. Conversely, a small force applied for a long time produces the same change in momentum—the same impulse—as a larger force applied briefly.

J = F(t − t)

The impulse is the integral of the resultant force (F) with respect to time:

J = ∫F dt

"Impulse" is the fifty-seventh episode of the American science fiction television series Star Trek: Enterprise, the fifth episode of season three. The episode was written by story editor Jonathan Fernandez from a story by Fernandez and Terry Matalas. It first aired October 8, 2003 on the UPN network in the United States. The episode was described by Paramount Pictures as "as close to a horror show as Star Trek gets".

Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In this episode, while investigating the Delphic Expanse for a Xindi superweapon, the Enterprise responds to the distress call of a Vulcan ship. The crew on board have undergone the effects of exposure to Trellium-D, which turns Vulcans into violent zombie-like drones.

Impulse is an elure manufactured by Fabergé which was part of Unilever, an Anglo- Dutch company based in Rotterdam, Netherlands, and London, United Kingdom. Introduced as a 'perfume deodorant' in South Africa in 1972, Impulse was launched in the UK in 1981, including the butterfly design and the slogan "Men can't help acting on Impulse."

Impulse, Inc. is a software company responsible for making several 3D modeling and rendering applications. Most notably TurboSilver and Imagine for the Amiga computer. They were originally located in Minneapolis, Minnesota and later moved to Las Vegas, Nevada. After moving to Las Vegas they became more and more involved in creating software for casino video slot machines.

An impulse is a wish or urge, particularly a sudden one. It can be considered as a normal and fundamental part of human thought processes, but also one that can become problematic, as in a condition like obsessive-compulsive disorder, borderline personality disorder, and attention deficit hyperactivity disorder.

The ability to control impulses, or more specifically control the desire to act on them, is an important factor in personality and socialization. Deferred gratification, also known as impulse control is an example of this, concerning impulses primarily relating to things that a person wants or desires.

Impulse (working title: Want a Ride, Little Girl?), is a thriller film, starring William Shatner as a serial killer of wealthy widows. Ruth Roman, Kim Nicholas, Jennifer Bishop, and Harold Sakata. It was written by Tony Crechales and directed by William Grefé. Its runtime is 82 minutes.

The film was first released in Tampa, Florida, on January 31, 1974, where the filming took place. It was subsequently released nationwide in 1974–75, making nearly $4 million in the domestic box office.

According to the Examiner.com interview, director Grefé cast actors who were located in Miami at the time. He met Shatner at the airport, Bishop was Grefé's friend, and Sakata had a wrestling career there apart from appearing in the James Bond-film Goldfinger. The filming lasted 15 days, including 12 with Shatner and last three with other actors. During one take of the scene where Shatner's character hangs Sakata's character to death, actor Sakata nearly died of being accidentally hanged by tight rope. Fortunately, with Sakata's "superior neck development", the crew was able to save his life. Shatner broke his finger during the incident while supporting Sakata's weight.

Impulse is a steel roller coaster located at Knoebels Amusement Resort in Elysburg, Pennsylvania. It is manufactured by Zierer and is the first major steel coaster located at Knoebels since the Whirlwind which closed in 2004.

Riders are restrained by a lap bar only which comes across the legs and the waist. The ride features small, 8 passenger trains, resulting in a low capacity.

The ride starts off by rounding a bend and then climbing the 98ft (30m) lift hill. The train then proceeds to go straight down and into the first inversion, a cobra roll. The train then goes into a vertical loop followed by a series of twists and turns around the vertical lift hill until it enters the final inversion, a zero g roll. The train then goes into a short, but intense, helix before the brake run and into the station. The complete ride is one minute and twenty seconds.

Riders can also purchase a photograph of themselves on the roller coaster after the ride is through.
