Due to the difficulty of oral medication with migraine-associated nausea and vomiting, Compazine is given either intravenously or intramuscularly for symptom relief -- usually in an emergency room, urgent care center, or clinic.
Force is an interaction between objects that causes them to change motion. So, when you opened your locker door, your hand applied a force to the door, causing it to change its motion. We measure force in newtons (N), the scientific unit for measuring weight. One newton is equal to about 0.22 pounds. So, a girl weighing only 100 lbs. would be equal to approximately 445 newtons, or her force due to gravity (F g).
A force in mechanics is a concept that has both a size and a direction. The net force acting on an object is the sum of the forces onto the object, taking into account both their sizes, and their directions. For example, if an object has two forces acting on it, with equal sizes but in opposite directions, then the net force will be zero (technically: a null vector). If instead the forces are of equal size and in the same direction, then the net force is equal to twice either force.
