Question

It acts on objects moving through a liquid or gas.

Answer 1

Answer:

Fluid friction.

Explanation:

Friction can be defined as a force that resists the relative motion of two objects when there surface comes in contact. Thus, it prevents two surface from easily sliding over or slipping across one another. Also, friction usually reduces the efficiency and mechanical advantage of machines but can be reduced through lubrication.

Generally, there are four (4) main types of friction and these includes;

I. Static friction.

II. Rolling friction.

III. Sliding friction.

IV. Fluid friction.

Fluid friction can be defined as a type of friction that acts on objects moving through a liquid or gas. A fluid refers to any physical substance that can flow and is able to take the shape of a container.
