In a collision, a force acts upon an object for a given amount of time to change the object's velocity. The product of force and time is known as impulse. The product of mass â¦ and velocity change is known as momentum change. In a collision the impulse encountered by an object is equal to the momentum change it experiences.Impulse = Momentum Change.
In addition to the locus coeruleus existing as a source of the neurotransmitter norepinephrine within the central nervous system, the adrenal gland can also release norepinephrine during a stress response into the bodyâs blood stream, at which point norepinephrine acts as a hormone in the endocrine system.
