Question

The statement given below is incorrect. Write the correct statements.

Force of friction always acts in the direction of applied force.

Answer 1

1. When a body is moved over the surface of another body by applying a force, the frictional force is developed between the two surfaces in contact.
2. Frictional force being a resistive force always acts opposite to the direction of the applied force.
3. Frictional force always hampers the motion of a body over the surface of another body because frictional force always acts opposite to the direction of the force causing the motion.

Thus the correct statement is the force of friction always acts opposite to the direction of applied force.
