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.
For other uses, see Escape velocity (disambiguation). In physics, escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a massive body. The escape velocity from Earth is about 40,270 km/h (25,020 mph). More generally, escape velocity is the speed at which the sum of an object's kinetic energy and its gravitational potential energy is equal to zero.
