viscosity
Viscosity describes the ability of FLUIDS(GASES or LIQuIDS)to flow. The property of flowing is called the
fluidity, resistance to flow is the viscosity. It is a type of FRRCTRON force. If an object is mo ved through a fluid, the fluid just next to the object is carried along with it. The
nearby fluid is therefore moving relative to the fluid further away from the object and the resistance which is produced pulls the object back. This backwards force from the viscosity can be reduced by STREAMLINING. Different fluids have different viscosities; a gas such as air has a very low viscosity, since the MoLEcuLEs in it do not puII on each other very much. A liquid such as cooking oil has a high viscosity because its molecules have long 'tails'on them which easily get tangled up and stop the molecules moving past each other.
