## What is the difference between upthrust and viscous drag?

The force of upthrust equals the weight of fluid displaced. Viscous forces are caused by relative motion between the body and a fluid. You can call it viscous drag. Examples include air resistance and water resistance.

Is viscous drag equal to upthrust?

This means that the forces acting on the object are balanced. This means that is it possible to form an equation be equating Weight with Upthrust and Viscous Drag (or, in the case of Upward Motion, Upthrust with Weight and Viscous Drag).

Is viscous drag greater than upthrust?

Comparing statements 1 and 2, up thrust is constant at H height and H−x BUT drag or viscous force increases as velocity of an object increases, so viscous drag is greater than up thrust.

### What is the difference between viscosity and buoyancy?

Viscosity is simply defined as the resistance of a liquid or gas to flow. Liquids and gases with low internal friction will flow very easily. Viscosity is different to buoyancy in that it describes internal forces within a substance, rather than an upward force exerted by a substance on another substance.

Is drag same as upthrust?

As nouns the difference between upthrust and drag is that upthrust is an upward thrust while drag is (uncountable) resistance of the air (or some other fluid) to something moving through it or drag can be (uncountable|slang) women’s clothing worn by men for the purpose of entertainment.

What is difference between viscous force and buoyant force?

Buoyant force being the upward force exerted by the liquid,upthrust being the reaction on a body and viscous force is the frictional drag on the body moving through liquid.

#### Is viscous force and upthrust the same?

They are the forces exerted by a fluid on a body when the body displaces some weight of the fluid. The force ofupthrust equals the weight of fluid displaced. Viscous forces are caused by relative motion between the body and a fluid.

What is difference between viscosity?

In simpler words, density = number of molecules x molecular weight/volume occupied, while the viscosity is a measurement of the inter-molecular forces and molecule shapes. Viscosity tells you the “friction” between two layers of the given fluid, while density varies slightly with temperature, viscosity changes rapidly.

What is viscous drag?

In a fluid, each ‘layer’ experts a force of friction of each other ‘layer’. This frictional force is also present when solid object moves through a liquid. This force is termed Viscous Drag.

## What is the difference between upthrust and viscous force?

1 – Upthrust is the force which acts in upward direction and normal to the motion of object while viscous force acts in tangential direction to the motion of object. Hope you have understood.

Is it possible to equate weight with upthrust and viscous drag?

This means that is it possible to form an equation be equating Weight with Upthrust and Viscous Drag (or, in the case of Upward Motion, Upthrust with Weight and Viscous Drag).

What is meant by upthrust?

This is called Upthrust. According to Archimedes’ Principle, the upthrust on an object in a fluid is equal to the weight of the fluid displaced. So the volume of the object multiplied by the density of the fluid. In a fluid, each ‘layer’ experts a force of friction of each other ‘layer’.
