Question

What is the direction of frictional force ?

Answer 1

Answer:

The frictional force is the other component; it is in a direction parallel to the plane of the interface between objects. Friction always acts to oppose any relative motion between surfaces. For the simple example of a book resting on a flat table, the frictional force is zero.

Answer 2

Friction is a force which opposes the motion of an object when the object is in contact with another object

Types :

# Static friction

# Kinetic friction

# Rolling friction

Static friction - a force that keeps an object at rest

Kinetic friction - a force that acts between moving surfaces

Rolling friction - when one body rolls over another , the resistance offered to motion is called rolling friction

$\star$The direction of force of friction is opposite to the direction of motion of body
