The change of momentum of a body or physical system over a time interval in classical mechanics, equal to the force applied times the length of … 2. a sudden uncontrollable determination to act. Learn what momentum and impulse are, as well as how they are related to force. In other words, if an object changes speed, then its momentum changes. It is represented by the symbol J and usually expressed in Newton-seconds or kg m/s. impulse [im´puls] 1. a sudden pushing force. pulse (ĭm′pŭls′) n. 1. a. Definition: Impulsive buying is the tendency of a customer to buy goods and services without planning in advance.When a customer takes such buying decisions at the spur of the moment, it is usually triggered by emotions and feelings. In order to perform the integral, it is necessary to know r at all times so that F may be known at all times. Pyromania is an example. An impulse is a sudden force or desire — this could be an electrical impulse, or an impulse to get some pizza. 3. The non-technical answer to this question is that an IR is a snapshot of a speaker cabinet’s linear characteristics. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction. 3. nerve impulse. With Maddie Hasson, Sarah Desjardins, Enuka Okuma, Craig Arnold. the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: 2. a sudden uncontrollable determination to act. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked.

impulse [im´puls] 1. a sudden pushing force. A person with impulse control disorder is unable to resist the sudden, forceful urge to do something that may cause harm. Courses. 3. nerve impulse. Learn what momentum and impulse are, as well as how they are related to force. Other articles where Impulse is discussed: mechanics: Collisions: …integral is known as the impulse imparted to the particle. Impulse in Physics is a term that is used to describe or quantify the effect of force acting over time to change the momentum of an object. Created by Jeffrey Lieber. 2. Impulse = Ft. The motion produced by such a force. Impulse is directly related to momentum because impulse is a term describing an object's change in momentum. From Newton's second law. The product of average force and the time it is exerted is called the impulse of force. See also point of maximal impulse. An impelling force; an impetus.
