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.
Fluid resistance, also known as viscous drag, is the force that opposes the motion of an object moving through a fluid, such as air or water.
20 lip 2022 · When a solid object moves through a fluid it will experience a resistive force, called the drag force, opposing its motion. The fluid may be a liquid or a gas. This force is a very complicated force that depends on both the properties of the object and the properties of the fluid.
13 sie 2024 · In physics, drag, also known as fluid resistance, is a physical force that opposes the motion of an object as it moves through a fluid, such as air or water.
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".
8 maj 2023 · Fluid resistance refers to the forces a fluid places on a moving object in the opposite direction to the movement, also known as drag. Drag is the force created by a fluid to resist the motion of an object through it.
A fluid is a state of matter that yields to sideways or shearing forces. Liquids and gases are both fluids. Fluid statics is the physics of stationary fluids. Density is the mass per unit volume of a substance or object, defined as \(\rho = \frac{m}{V}\). The SI unit of density is kg/m 3.
