Drag force

Definition

The drag force is a resistive force that opposes the motion of an object through a fluid (such as air or water). It depends on the shape and speed of the object.

Related terms

Terminal velocity: The maximum speed an object can reach when falling through a fluid due to the balance between gravity and drag force.

Streamlined shape: A shape designed to minimize drag by reducing turbulence and smoothly guiding fluid around it.

Viscosity:

A measure of how resistant a fluid is to flow, affecting the magnitude of drag force experienced by objects moving through it.
