When an object falls under the influence of [[gravity]], the resistance due to the presence of air molecules creates drag. As the object keeps accelerating the drag increases proportionally and reaches a point where the drag force balances the weight of the falling object. Sometimes, if the object has a [[buoyancy|buoyant]] force, it is added up to the forced caused due to drag. At this point, the object can no longer accelerate and reaches the constant velocity, known as the terminal velocity. |
At terminal velocity, the gravitational force acting on it is equal to the force of drag exerted by the fluid. Mathematically, terminal velocity can be formulated by analyzing the total force acting on it. | At terminal velocity, the gravitational force acting on it is equal to the force of drag exerted by the fluid.
