Friction is necessary to make motion rolling but if the body is already in rolling motion on rough surface without slipping then, is friction necessary to continue the rolling motion ?
No, not if the surface is horizontal. Once an object is rolling along a horizontal surface, no static friction is required to maintain that rolling motion. (Of course, in 'real life' deformation and rolling friction will slow the object down.)paragchitnis said:Friction is necessary to make motion rolling but if the body is already in rolling motion on rough surface without slipping then, is friction necessary to continue the rolling motion ?
In an abstract, imaginary situation, the object would just happen to be rotating at a rate where it's circumference surface speed is the same as the speed that the object is moving forwards.a.ratnaparkhi said:Friction force occurs due to cold locking between the crests and troughs of rough surface and the surface of the body. So without such locking, how could it roll?
Rolling motion on rough surfaces refers to the movement of an object, such as a ball or a wheel, as it rolls along a surface with irregularities or bumps. This type of motion is affected by factors such as friction, surface texture, and the shape of the object.
Friction plays a crucial role in rolling motion on rough surfaces. It acts in the opposite direction of the rolling motion and can either slow down or speed up the object depending on the surface and the force applied. Rough surfaces tend to have higher levels of friction, which can make it more difficult for an object to roll smoothly.
The main difference between rolling motion on rough surfaces and smooth surfaces is the presence of friction. On a smooth surface, there is less friction, allowing for smoother and faster rolling motion. On the other hand, rough surfaces have more friction, which can cause the object to slow down or move erratically.
Surface texture refers to the physical characteristics of a surface, such as its roughness or smoothness. It can affect rolling motion on rough surfaces by altering the amount of friction present. A smoother surface texture will have less friction and allow for smoother rolling motion, while a rougher surface texture will have more friction and impede the object's movement.
Understanding rolling motion on rough surfaces has many practical applications, such as in the design of vehicles, sports equipment, and machinery. It also plays a crucial role in industries such as manufacturing and transportation, where the movement of objects on rough surfaces is common. Studying rolling motion on rough surfaces can help improve efficiency, reduce wear and tear, and enhance safety in these applications.
