Understanding the basics. • Terminal Velocity • Volume and density. • Resistance and pressure. 8
Terminal Velocity – Wikipedia ® An object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the air A free-falling object achieves its terminal velocity when the downward force of gravity (F g ) equals the upward force of drag (F d ). This causes the net force on the object to be zero, resulting in an acceleration of zero. As the object accelerates (usually downwards due to gravity), the drag force acting on the object increases, causing the acceleration to decrease. At a particular speed, the drag force produced will equal the object's weight (mg). At this point the object ceases to accelerate altogether and continues falling at a constant speed called terminal velocity (also called settling velocity). Terminal velocity varies directly with the ratio of weight to drag. More drag means a lower terminal velocity, while increased weight means a higher terminal velocity.
