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.
In this case, the terminal velocity increases to about 320 km/h (200 mph or 89 m/s), which is also the maximum speed of the peregrine falcon diving down on its prey. An object falling will fall 9.81 meters per second faster every second (9.81 m/sÂ²). The reason an object reaches a terminal velocity is that the drag force resisting motion is directly proportional to the square of its speed. At low speeds the drag is much less than the gravitational force and so the object accelerates.
