drag force
Movement through fluid
Drag force is the resistance that a fluid—whether liquid or gas—exerts on an object moving through it.
This force acts opposite to the direction of motion and increases with the object's speed, size, and the density of the surrounding medium.
Engineers and physicists calculate drag force when designing vehicles, aircraft, and projectiles to optimize their movement through air or water.
Streamlined shapes reduce drag force and improve fuel efficiency.
