FranYes, friction can happen in a liquid. When an object moves through a liquid, such as water, the liquid molecules provide resistance to the object's motion, creating a force opposing its movement. This resistance is known as viscous drag, and it is a form of friction that occurs in liquids.

What is internal friction in liquid?
Internal friction in a liquid refers to the resistance encountered by the liquid molecules as they flow past each other. It is a measure of how easily the liquid can respond to external forces and deformations. Internal friction affects the viscosity of the liquid, with higher internal friction leading to higher viscosity.
How does Friction occur in liquids?
Friction in liquids is caused by the interaction of molecules as they move past each other. The viscosity of a liquid, which is its resistance to flow, determines how much friction there is in the liquid. When molecules in a liquid move, they create resistance against each other, leading to friction.
What term refers to one internal friction of a liquid?
Viscosity is the term that refers to the internal friction of a liquid, which describes its resistance to flow.
Does friction occurs only between solids?
No, friction can occur between any two surfaces in contact, regardless of whether they are both solids. Friction can also occur between a solid and a liquid, a liquid and a liquid, or a solid and a gas.
What type of friction acts on a spoon when you stir it?
Kinetic friction acts on a spoon when you stir it. As the spoon moves through the liquid, friction between the spoon and the liquid causes resistance, making it harder to stir.
