what is friction? what is fluid friction? what is rolling friction?
Answers
what is friction
a push are a pull acting on an object is called force .the SI unit of force is Newton we use pers to perform various activities.
what is fluid friction
when an object moves in the fluid lead liquid or gas it experience a force that tends to slow it down these resistive force is called drag .
what is rolling friction
the frictional force offered bin rolling and object is called rolling friction for example a ball rolling on a surface
Answer:
The force which always opposes the motion of one object in contact with it is called friction .
Explanation:
ROLLING FRICTION:-
when am object rolls over the surface of another object,the resistance to the motion is called rolling friction .
FLUID FRICTION:-
liquid and gases are fluids . The frictional force exerted by these gases and fluid are called fluid friction.
