Question

What is friction descibe​

Answer 1

Answer:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

Answer 2

${\huge{\bold{\underline{\texttt{\orange{Answer}}}}}}$

Friction - Frictional force is the force acting against the relative motion of the surface of the bodies in contact .

Frictional force always acts in the opposite direction .

If we apply the force along the left , friction acts along the right . If we apply the force along the right direction , the friction acts along the left direction .

Causes of friction :-

I. Due to the interlocking between the surfaces .( roughness between two surfaces )

II. Due to the force of adhesion between the two surfaces .

Types of friction :-

I. Static Friction

II. Sliding Friction

III. Rolling Friction

Effects of Friction :-

I. Wear and tear of machine parts are caused due to friction

II. Heat is produced .

III. Motion is opposed .
