In which direction does friction act compared o the direction of movement?
Friction acts opposite to the direction of movement. It resists the sliding or rolling motion of objects in contact with each other.
Why is there friction between two plates even though they are moving in the same direction?
Friction between two plates moving in the same direction arises due to irregularities on the surfaces that interlock, creating resistance to the relative motion. This resistance occurs because the contact points between the surfaces experience strong forces that oppose the motion.
Is the coefficient of friction constant in this scenario?
In this scenario, the coefficient of friction is constant if the surfaces in contact and the conditions remain the same.
Why is rolling friction is lesser than sliding friction?
Rolling friction is generally lower than sliding friction because when an object is rolling, only the point of contact is experiencing friction, while in sliding friction, the entire surface of contact is experiencing friction. In rolling, the point of contact continually changes, reducing the resistance to motion compared to sliding where the contact surface remains the same.
State laws of limiting friction?
1. the direction of force of friction is always opposite to the direction of motion.. 2. the magnitude of limiting friction depends upon the nature and state of polish of the two surfaces in contact and acts tangentially to the interface between them.. 3. the magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.. 4. the magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same..

Does friction move in the same direction as or in opposite direction as the object?
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.

Friction between two plates moving in the same direction arises due to irregularities on the surfaces that interlock, creating resistance to the relative motion. This resistance occurs because the contact points between the surfaces experience strong forces that oppose the motion.
Is friction in same direction of force?
This question is ambiguous. It depends on what force you are comparing the friction force with. Friction, itself, is a force, which will be directed in a direction OPPOSITE the sliding or attempted sliding of two surfaces.

In this scenario, the coefficient of friction is constant if the surfaces in contact and the conditions remain the same.

Is the coefficient of friction the same as when the block was standing on its larger (or smaller) end?
No, the coefficient of friction can vary based on the contact surface area and material properties of the block. When the block is standing on its larger (or smaller) end, the contact surface area and the weight distribution changes, which can affect the coefficient of friction.
What do to forces in the same direction cause?
Forces in the same direction will add together, resulting in a stronger overall force. This is known as constructive interference or reinforcement of forces.
The force of friction is directed opposite of the way an object is moving because?
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.
Is friction is a non-contact force?
a contact force requires two bodies to either touch each other(are in contact) or are interacting through a medium(rope, pole). example of contact force is friction.
Does rolling friction push the same direction as the velocity of an object?
If it did, then any rolling object would speed up because of friction. Since everythingthat rolls actually slows down, the virtual 'force' of friction must be exactly oppositethe direction of an object's motion.
