In aerodynamics, aerodynamic drag, also known as air resistance, is the fluid drag force that acts on any moving solid body in the direction of the air's freestream flow. From the body's perspective (near-field approach), the drag results from forces due to pressure distributions over the body surface, symbolized .
As an object falls through air, it usually encounters some degree of air resistance. Air resistance is the result of collisions of the object's leading surface with air molecules. The actual amount of air resistance encountered by the object is dependent upon a variety of factors.
The force on an object that resists its motion through a fluid is called drag. When the fluid is a gas like air, it is called aerodynamic drag or air resistance. When the fluid is a liquid like water it is called hydrodynamic drag, but never "water resistance". Fluids are characterized by their ability to flow.
29 lip 2022 · Falling Object with Air Resistance. Force. An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object, and the second force is the aerodynamic drag of the object.
8 cze 2023 · Air resistance, also known as drag, is a force that opposes the motion of an object as it moves through the air. It is an important concept in physics and plays a significant role in various fields, including engineering, sports, and aerodynamics.
17 maj 2016 · Definition: By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the...
In this explainer, we will learn how to define air resistance and describe the factors that affect it. We have already learned about friction and how it resists motion when two solid objects move over each other.
