Question

What kind of friction does a fish experience as it swims through water?

Answer 1

Answer:

Fluid Friction

Explanation:

The kind of friction that occurs when a fish swims through water is fluid friction. The name alone is a giveaway since water is a fluid. By definition, fluid friction is the resistance to an object's movement through a fluid, where a resistance to a movement through fluid is also termed as viscous resistance.

Answer 2

Answer:

Drag or hydrodynamic drag

Explanation:

The general name for friction caused by a fluid's viscous forces is called drag or fluid resistance.

When the fluid is a gas, we call it air resistance or aerodynamic drag.

When the fluid is liquid, we call it hydrodynamic drag.
