What is Friction Force?

Answer 1

YES, YEA it is

Yes it is a force. If not then we would be slipping around. What i have heard is that friction causes a pull in some ways. Say you slid a pencil on the floor with nothing in it's path. Now if you know what inetia (not a force) then you would know that the pencil would stop because of a outside force. And that force is friction. Friction had reduced the pencils speed when it rubbed together on the floor. Now if the pencil was givin more force when you pushed it and the floor was more slik then the pencil would have traveled alot more. This is because the force of friction is a less amount when one surface is smoother. I know this is a horrible explanation but this is what helps me think of the forces. And this is going to prove to my teacher that friction is a force and that inertia is not.

Answer 2

Friction is the interaction between two touching surfaces which opposes the sliding of the two surfaces across each other. No motion is required for friction to be present. In fact, friction can actually cause an object to move, starting from rest. Consider a book resting on a piece of paper on a table. Pull the paper gently and the book will move. This is because of the friction between the book and the paper. The friction pulls the book in the same direction the book is moving.

Answer 3

Frictional force is the force that opposes motion between two surfaces.

Answer 4

Friction Force- this is the force exerted by a surface on an object & opposes the motion of the object.
