Rolling friction is the force of friction between two surfaces when one surface rolls over another.Sliding friction is the force of friction between two surfaces when one surface is moving on another.
Sliding friction is the force that opposes the motion of an object sliding along a surface. Rolling friction, on the other hand, is the force that opposes the motion of an object rolling over a surface. Rolling friction is generally less than sliding friction, making it easier for objects to move when rolling rather than sliding.
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.
Sliding friction is generally greater than rolling friction because sliding friction occurs when two surfaces slide past each other, creating more contact and resistance compared to rolling friction, where an object rolls over a surface with less resistance.
You need a smaller force for rolling because rolling friction is typically smaller than sliding friction. Rolling involves the object rotating along its surface, leading to a smaller contact area and less resistance compared to sliding, where the entire object is in contact with the surface, resulting in higher friction.
I assume this relates to a wheel. When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction. When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
No.
Rolling friction generates considerably less heat than sliding friction. .

Generally, sliding friction is much stronger than rolling friction.
Rolling kinetic friction is usually less than sliding kinetic friction. This is because rolling friction involves less resistance as the object rotates on a surface, compared to the resistance in sliding friction where surfaces slide past each other.
friction is a eorce of contact between two surfaces which opposes motion of objects over one another. In rolling friction the area in contact between two objects is comparatively less then that in case of sliding as in rolling, one object just roll over each other hence area of contact is less so force of rolling friction is less than sliding friction.
Friction is a force between to surfaces that resists motion. Static friction is the resistance to motion when two surfaces are not moving relative to each other. Sliding friction is the resistance to motion when two surface are sliding, one over the other. Sliding friction is less than static friction for the same two surfaces. For rolling friction an object is rolling, like a tire on a road. It's what provides traction between the two and makes the car "go." For a tire on a road, rolling friction is less than sliding friction.
Yes, sliding friction creates more thermal energy and wears down the two surfaces quicker than rolling friction.
Rolling friction is the resistance encountered by an object when it rolls over a surface. It is typically less than sliding friction because the object's shape allows for smoother movement. Rolling friction occurs between the object and the surface it is rolling on.
== == AnswersIt is easier to stop sliding friction than rolling friction. The force due to sliding friction will always be greater than the force due to rolling friction. And since friction force will be in the opposite direction of motion it will be easier to stop an object in motion that is sliding than one that is rolling.
