For objects moving through air at subsonic speeds, this often involves the drag coefficient, the fluid density, the cross-sectional area, and the gravitational acceleration. In denser fluids, such as water, drag is much greater than in air, causing objects to reach their terminal speed more quickly and at a lower value.
Terminal Velocity Definition Physics Parachute Effect and How Drag Slows Descent
Mathematical Expression and Variables The terminal velocity definition physics can be captured in a formula where drag force is set equal to gravitational force. How Gravity and Drag Create Equilibrium As an object begins to fall, it accelerates due to gravity, but the surrounding fluid—air or liquid—generates a drag force that increases with speed.
This interplay between mass and cross-sectional area explains why a heavy skydiver in a streamlined position falls faster than one who spreads their limbs to increase air resistance. Raindrops do not grow indefinitely because they reach a terminal velocity that prevents them from shattering upon impact.

Eventually, the drag force grows to match the gravitational pull, establishing a balance where the net force is zero. Conversely, objects with a large surface area relative to their mass, such as a feather or a parachute, experience more drag and reach a lower terminal velocity.
