Liquid friction refers to the resistance encountered when an object moves through a liquid due to interactions between the object and the liquid molecules. It is also known as viscous drag and is influenced by factors such as the viscosity of the liquid and the speed and shape of the object moving through it. It plays a role in various fluid dynamics applications, such as in the flow of water through pipes or the movement of ships through water.
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.
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.
Viscosity is the term that refers to the internal friction of a liquid, which describes its resistance to flow.
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.
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.
