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.

What is the force that opposes the friction force?

The opposite force to friction is momentum. Because friction stops an object from moving or slows an object down, momentum keeps it at speed.


Does friction cause the speed of moving objects to increase?

No, the force of friction always acts in the direction opposite to that of the motions.


What direction does friction act in to an object's direction of motion?

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.


How does the direction of friction compare to the direct motion?

The direction of friction is opposite to the direction of motion. This means that when an object is moving in one direction, the friction force is acting in the opposite direction, trying to slow down or stop the object.


Why is the force of friction directed the opppsite way of an object that is movin?

I never thought about it before, but here's one way to look at it:Forces on a moving object that act in the same direction it's moving make it go faster.Forces on a moving object that act opposite to the direction it's moving make it go slower.Friction never makes things go faster, or ... heaven forbid ... makes stationary things start moving.Friction only makes it hard to make things start moving, and it slows them down once they move.


What are forces between two moving objects that are touching?

Friction force. [opposite force]


What is the friction that prevents an object from moving when a force is applied is what friction?

Static friction is the friction that prevents an object from moving when a force is applied. It acts in the opposite direction of the applied force and increases until the force surpasses the maximum static friction force, allowing the object to move.


In what direction is static friction acting?

Static friction acts in the opposite direction of the applied force, preventing an object from moving when a force is applied to it.


How does friction affect the motion of a moving object?

Friction acts in the opposite direction to the motion of the object, slowing it down. It transforms kinetic energy of the moving object into heat energy. The amount of friction depends on the surfaces in contact and the force pushing them together.


What happen friction force stop moving?

When friction force stops an object from moving, it is because the opposing force of friction is greater than the force trying to move the object. The friction force acts in the opposite direction of the applied force, ultimately bringing the object to a stop. This occurs when the static friction force between the object and the surface it is on overcomes the force trying to make the object move.


How do you apply friction?

Friction acts in the opposite direction that the object is moving or trying to move. The force of friction is calculated by multiplying the normal force of the object, usually mass times gravity, by the coefficient of friction.


Would you slow down or keep moving if there wasn't much friction?

You would keep moving, because friction is what slows you down.
