it acts in the opposite direction of motion or force
Friction acts in the direction opposite to that of the motion or, if the friction is too large for actual motion, the direction of potential motion.
The "force" of friction is always exactly opposite the direction of motion.
Friction always acts in the opposite direction to that of the motion of the other object. Meaning, friction slows down the motion of an object by exerting opposing forces on it.
Friction acts to inhibit or "decrease" motion. Friction applies to any moving object, and will always act to slow it down or resist a change in its direction of motion.
Friction always acts in the direction opposite to the the motion of the object.For example, if a bowling ball rolls to the right, friction would act to the left.Without friction, if you threw a ball, it would keep going forever. Friction slows objects down.
Friction always acts in the opposite direction to that of the motion of the other object. Meaning, friction slows down the motion of an object by exerting opposing forces on it.
Frictional force must always act in opposite directions
Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.

no limiting friction is not less than rolling friction
