Question

about static and sliding friction​

Answer 1

Answer:

$\huge{\underline{\bold{\red{Answer :-}}}}$

• Static friction is the force which acts between two bodies when a force is applied on a body but there is no relative motion between the surfaces. Static friction opposes impending motion. It is denoted by fs law of static friction is given by:

fs ≤μsN

where μ s

• is the coefficient of static friction and depends only on the nature of the surfaces in contact. N is the normal force.

Explanation:

SLIDING FRICTION - DEFINITION

• The Sliding Friction is friction which comes into play when surface of one object moves relative to surface of another object. It is also called as kinetic friction. It is that force that keeps a surface sliding with another surface. For example, if book is kept on floor and the book moves with respect to the floor.

• It is the frictional force between two surfaces that are rubbing against each other. It’s hard to find a perfectly smooth surface in the real life, therefore when an object slides on any surface, it undergoes a backward force because of the relative motion between the two adjacent surfaces. It always acts against the motion.

Answer 2

$static \: friction$

Static friction is the force which acts between two bodies when a force is applied on a body but there is no relative motion between the surfaces. Static friction opposes impending motion.

$sliding \: friction$

The Sliding Friction is friction which comes into play when surface of one object moves relative to surface of another object. It is also called as kinetic friction. It is that force that keeps a surface sliding with another surface.
