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.
Stress is a very common cause of constipation. Stress affects the body in many different ways, including activating the sympathetic nervous system (fight or flight response). Certain body types will react to stress by decreasing the movement of the bowels (peristalsis). In stressful situations, people sometimes will eat unhealthy diets, decrease the amount of exercise they perform, and drinking less water, which are all very common causes for constipation.
