Friction always acts "________" to the surface.

In the figure shown, force of friction on A from B will always be right wards Friction always opposes the relative motion between two bodies in contact.

Fill in the following blanks with suitable words : Friction always opposes………………………between the surface in contact with each other .

Assertion : Friction always opposes the motion. Reason : Whenever one surface moves or tries to move over another surface, the force of friction starts acting on the surfaces.

STATEMENT -1 : Friction always opposes motion . STATEMENT - 2 : Lesser the friction on a surface it is easier to walk on it. STATEMENT -3 : Soles of shoes gets flat due to friction .

Statement 1: While drawing a line on a paper by pencil, friction force acts on paper in the same direction along which line is drawn on the paper. Statement 2: Friction always opposes motion.

Choose the correct options – (1) Friction always opposes the motion (2) Friction may opposes the motion (3) If the applied force is increased the force of static friction remains constant. (4) If the applied force is increased the force of static friction also increases upto limiting friction.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following four responses Assertion: Friction always opposes the relative motion of two bodies. Reason: Without friction also, one can move on a smooth surface.
