Air resistance is the opposing force experienced by objects moving through air. It depends on factors such as speed, size, and shape of the object.
Drag Force: The force that opposes the motion of an object through a fluid (liquid or gas).
Terminal Velocity: The constant velocity reached by an object falling through a fluid when the drag force equals the gravitational force.
Streamlining: The process of shaping an object to reduce air resistance and improve its aerodynamic properties.
