Sugarless gum can also be used as a vehicle to deliver medicaments that may benefit oral and systemic health. Chewing gum products can be formulated to assist caries reduction by remineralization or neutralization of plaque acid.
The net force on the object then, is zero, and the result is that the velocity of the object remains constant. Terminal velocity is the highest velocity attainable by an object as it falls through a fluid (air is the most common example, but the concept applies equally to any fluid). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object.
An upward vertical velocity of just 6 centimeters per second can produce a large volume of precipitation if the moisture is present to be condensed. Let's apply upward vertical velocity to interpreting the synoptic scale forecast models (NAM,GFS etc.). Upward vertical velocity is plotted on the 700-mb prog. Go ahead and look at a 700 mb forecast panel on your computer. This prog is available on UNISYS weather at: You will see a panel full of colors, wind vectors, and height contours. The colors are the upward and downward vertical velocities.
