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.
We all know that stress can make us feel upset, agitated and sometimes overwhelmed. The question is how does stress affect our body and our mind, and what can we do about it?

This controls all of the processes that you do without thinking, such as breathing, digestion and your heart beat. Within the autonomic system there are two systems of interest, which work in tandem with each other.
