What is friction? In which direction does it apply?

What is the magnetic dipole moment of a current loop? In what direction does it act?

(a) In which direction does conventional current flow around a circuit? (b) In which direction do electrons flow?

What is dry friction ? And what is wet friction ?

A force F is applied horizontally on a cylinder in the line of centre as shown in the figure. The cylinder is on a rough surface of coefficient of fricition mu . The direction of the friction force acting on the cylinder will be

What are the factors on which friction is not dependent ?

A particle of mass m rests on a horizontal floor with which it has a coefficient of static friction mu . It is desired to make the body move by applying the minimum possible force F. Find the magnitude of F and the direction in which it has to be applied.

A blocky of mass m rests on a horizotal floor with which it has a coefficient of static friction mu. It is desired to make the body move by applying the minimum possible force F. Find the magnitude of F and the direction in which it has be applies.

If the direction of applied force and direction in which an object moves are perpendicular to each other then:
