The drag force experienced by an object is directly influenced by the relative velocity between the object and the fluid, specifically air. Wind alters the velocity of air particles, thereby affecting the drag force acting on vehicles such as planes and cars. This relationship is consistent with principles established in Newtonian physics and Special Relativity. Testing in wind tunnels demonstrates that the drag force can be evaluated by manipulating the air velocity rather than the object's movement.
PREREQUISITESAerospace engineers, automotive engineers, physics students, and anyone interested in fluid dynamics and drag force analysis.
Drag force depends on the velocity difference between fluid and object. It doesn't matter which is moving. Planes and cars are tested in wind tunnels, where the air is moving instead of the vehicle.GuMing said:The drag force can be affected by the velocity of the object relative to the fluid. Does that mean the wind affects the drag force, since it changes the velocity of air particles?
