This is a type of friction experienced within liquids and gases. it depends on:
(1) how thick the fluid
(2) how the shape of the object?
(3) how the speed of the object?

(1) how thick the fluid is viscosity

Explanation:

This is a type of friction experienced within liquids and gases. It depends on:.

(1) how thick the fluid is?

(2) how the shape of the object?

(3) how the speed of the object?

the thickness of a fluid is known as viscosity. the more viscous a fluid is the more frictional force is exerted on an object by the fluid

frictional force is an opposing force that resist the movement of two surfaces in contact, there are to types 0f frictional force

1. static frictional force

2. dynamic frictional force

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
