Impulse has the same units and dimensions (MLT −1) as momentum. In the International System of Units, these are kg⋅m/s = N⋅s. In English engineering units, they are slug⋅ft/s = lbf⋅s. The term "impulse" is also used to refer to a fast-acting force or impact.
Impulse (physics), in mechanics, the change of momentum of an object; the integral of a force with respect to time Impulse noise (disambiguation) Specific impulse, the change in momentum per unit mass of propellant of a propulsion system
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, [24] [unreliable medical source?] borderline personality disorder, attention deficit hyperactivity disorder, or in fetal alcohol spectrum disorders.
If mass is used, specific impulse is an impulse per unit of mass, which dimensional analysis shows to be equivalent to units of speed; this interpretation is commonly labeled the effective exhaust velocity. If a force-based unit system is used, impulse is divided by propellant weight (weight is a measure of force), resulting in units of time.
True pyromaniacs — people with an impulse disorder characterized by a compulsive need to set things on fire — do exist, but they are a rare breed. Studies have found that less than 10% of ...
These impulse responses can then be utilized in convolution reverb applications to enable the acoustic characteristics of a particular location to be applied to target audio. [4] In electric guitar signal processing and amplifier modeling, impulse response recordings are often used by modeling software to recreate the recorded tone of guitar ...
In physiology, the all-or-none law (sometimes the all-or-none principle or all-or-nothing law) is the principle that if a single nerve fibre is stimulated, it will always give a maximal response and produce an electrical impulse of a single amplitude. If the intensity or duration of the stimulus is increased, the height of the impulse will ...
Goldberg used "suicide pact" in similar fashion the following year in Aptheker v. Secretary of State , quoting himself in a decision that rejected a law barring Communist Party members from ...
