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.
Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/sÂ², independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 56 m/s (200 km/h or 120 mph) for a human body.
