Friction's direction is always against the direction work is being applied to.
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
The force of friction ALWAYS acts in the direction exactly opposite to the directionin which the object is moving.If the friction force acted in the same direction as the object's motion, then youwould want to have as much friction as possible, because that would help youmove the object with less fuel.
All types of friction act opposite to the direction of motion but static friction is the friction present before motion occurs.
The force of friction is NOT ALWAYS directed opposite the direction an object is moving. Consider, for example, an object (like a book) resting on a piece of paper on a table. If you gently pull the paper and the book moves with the paper, friction between the paper and the book is causing the book to move in the same direction as the paper. Even if you pull a bit faster and the book slides in the same direction as the paper motion, but a little bit slower, the friction is the force which is pulling the book along--in the same direction of the paper motion.The direction friction is acting is opposite the direction of the relative SLIDING or attempted sliding of surfaces. In the cases above, without friction, the book would slide opposite the direction of paper motion, so the friction is in the same direction, accelerating the book along with the paper. In the first case, the book's acceleration is the same as the paper's; in the second, the book's acceleration is less than the paper's causing the book to actually slide backwards relative to the paper's motion.
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
Friction's direction is always against the direction work is being applied to.
Friction always acts opposite to the direction of motion.
Friction always acts opposite to the direction of motion.
Friction always acts in the opposite direction, of the other object's motion.
The "force" of friction is always exactly opposite the direction of motion.
Friction is always against the direction of the movement.
Friction provides a retarding force. It always acts in the exact opposite direction of the motion of the object.
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 provides a retarding force. It always acts in the exact opposite direction of the motion of the object.
And it not only DOES; it works in no other way. Friction is a sneaky thing. You know how a thermos "knows" to keep the hot stuff hot and the cold stuff cold? Well, friction always knows in which direction you're trying to go and pushes against you!
it acts in the opposite direction of motion or force
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
