What is bed deformation?
The upper layers of the bed materials are deformed by the frictional drag of the overlying ice. Unconsolidated material will act like a ball bearings and allow the glacier to move forward.
What is the force called between liquid particles?
viscosity. Viscosity is the inherent force of a liquid which opposes the relative movement between layers of the said liquid.
The SI unit of the drag force?
If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.
How do glaciers erode?
As glaciers move over any earth surface, they carry rocks, stones and boulders with them. These are at the bottom of the glacier under very high pressures. As the glacier moves it is this carried material that grinds away at the mountain underneath. This is what causes the errosion.
How do you explain air resistance?
In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas).Drag forces act in a direction opposite to the oncoming flow velocity.[1] Unlike other resistive forces such as dry friction, which is nearly independent of velocity, drag forces depend on velocity.[2]For a solid object moving through a fluid, the drag is the component of the net aerodynamic orhydrodynamic force acting opposite to the direction of the movement. The component perpendicular to this direction is considered lift. Therefore drag opposes the motion of the object, and in a powered vehicle it is overcome by thrust.In astrodynamics, and depending on the situation, atmospheric drag can be regarded as an inefficiency requiring expense of additional energy during launch of the space object or as a bonus simplifying return from orbit.
What is drag in scientific terms?
Drag is a frictional force which opposes movement of a mass.
What is the fricitional force that opposes the movement of object that fall through the air?
The frictional force that opposes the movement of an object that falls through the air is air resistance, or drag.
What is bed deformation?
The upper layers of the bed materials are deformed by the frictional drag of the overlying ice. Unconsolidated material will act like a ball bearings and allow the glacier to move forward.
What is frictional resistance due to motion through air?
This frictional resistance known as "air resistance" is the drag force. The drag force changes with the drag coefficient of the object in motion.
What is frictional force exerted by fluids called?
Drag. But it is often ok to just call it friction.
Frictional resistance due to motion through air?
air drag
What is the name of the frictional force between the surface and the air?
Viscous drag
What is the name of the force that always acts against the direction of movement?
In geneal frictional force. If it rubs against a surface then it is known to be friction. If it drags the moving body then it is said to be viscous drag.
VISCIOUS DRAG / VISCOSITY?
Opposing / Frictional force involving a fluid. It limits the speed with which a body can move in a liquid
Force that resits motion?
Force that resists motion is frictional force, viscous drag
Solid object moves through the air the particles knock the bumps on the surface What is the name of the frictional force?
Drag.
What is frictional drag?
Friction drag is the drag acting on the surface of an object from a fluid flowing over it. When a fluid flows over an object it exerts a shear force on the object because of the fluid's viscosity which pulls the object in the direction of the flow.
