1.	Can we predict the direction of motion of a body from the direction of force on it
Answer» Solution :Yes. The direction of motion is always opposite to the FORCE of KINETIC friction. By USING the principle of equilibrium, the direction of force of static friction can be DETERMINED. When the object is in equilibrium, the frictional force must point in the direction which RESULTS as a net force is zero.
