Drag (physics) - Wikipedia
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. [1] . This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface.
Drag Force: Definition, Formula, and Examples - Science Facts
2023年2月2日 · The resistance offered by a fluid, like air and water, is called the drag force or drag when an object moves through it. It acts in a direction opposite to the object’s motion. It is generated by the relative velocity between the solid object and the fluid.
5.2: Drag Forces - Physics LibreTexts
Like friction, the drag force always opposes the motion of an object. Unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid. This functionality is complicated and depends upon the shape of …
What is Drag? | Glenn Research Center | NASA
2022年7月21日 · Drag is the aerodynamic force that opposes an aircraft’s motion through the air. Drag is generated by every part of the airplane (even the engines!). How is drag generated? Drag is a mechanical force. It is generated by the interaction and contact of a …
Drag equation - Wikipedia
In fluid dynamics, the drag equation is a formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is: = where
5.2 Drag Forces - College Physics 2e - OpenStax
You feel a smaller drag force when you tilt your hand so only the side goes through the air—you have decreased the area of your hand that faces the direction of motion. Like friction, the drag force always opposes the motion of an object. Unlike simple friction, the drag force is proportional to some function of the velocity of the object in ...
6.4 Drag Force and Terminal Speed - University Physics Volume 1
Drag Forces. Like friction, the drag force always opposes the motion of an object. Unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid. This functionality is complicated and depends upon the shape of the object, its size, its velocity, and the fluid it is in.
6.7: Drag Force and Terminal Speed - Physics LibreTexts
Drag forces acting on an object moving in a fluid oppose the motion. For larger objects (such as a baseball) moving at a velocity in air, the drag force is determined using the drag coefficient, the …
