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.
How does glaciers erode by abrasion?
Glaciers erode by abrasion when they drag rocks and sediments along their base and sides, creating a sandpaper effect. This process occurs as the glacier moves, grinding, scratching, and smoothing the underlying bedrock and carving out deep valleys. The debris carried by the glacier further enhances the abrasion process as it scrapes against the surface.
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 you calculate drag coefficient when you are not given drag force?
You can calculate the drag coefficient by using the formula Cd = Fd / (0.5 * ρ * A * V^2), where Cd is the drag coefficient, Fd is the drag force, ρ is the air density, A is the reference area, and V is the velocity of the object. Given these values, you can rearrange the formula to solve for the drag coefficient.
What is basal drag force?
Basal drag force is the resistance on a glacier's base as it moves over its bed. It occurs due to the friction between the glacier and the underlying rock or sediment. The amount of basal drag force can affect the speed and movement of the glacier.
What is frictional resistance due to motion through air?
Frictional resistance due to motion through air is the force that opposes the movement of an object through the air. It is caused by air particles colliding with the surface of the object, creating a drag force that slows down the object's motion. The amount of frictional resistance depends on factors like the object's shape, speed, and the viscosity of the air.
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 fricitional force that opposes the movement of object that fall through the air?
The frictional force that opposes the movement of an object falling through the air is called air resistance or drag. It occurs due to the interaction between the object and the air particles as the object moves through the air. Air resistance slows down the object's descent and reduces its acceleration towards the ground.
What is the name of the frictional force between the surface and the air?
Viscous drag
Frictional resistance due to motion through air?
air 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.
Force that resits motion?
Force that resists motion is frictional force, viscous drag
What is frictional force exerted by fluids called?
The frictional force exerted by fluids is called drag force. This force acts opposite to the motion of an object as it moves through a fluid, such as air or water, and it can affect the speed and direction of the object.
VISCIOUS DRAG / VISCOSITY?
Opposing / Frictional force involving a fluid. It limits the speed with which a body can move in a liquid
What is drag in scientific terms?
In scientific terms, drag is a force that resists the motion of an object through a fluid (like air or water). It is caused by the friction and turbulence between the object and the fluid, resulting in a backward force that opposes the object's motion. Drag can significantly affect the speed and efficiency of moving objects, such as airplanes or cars.
What is the definition of viscous drag in an oil lubricant?
If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle. Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow). The viscous drag force increases linearly with the speed of the fluid.
