you can say it when greg bodner reaches the age of 64 and becomes a shrine we all know roke blas bamba is also a shrine god bless America and England
In general, we can say a surface is smooth if it's lack of any "grip" or textural features presents no friction.
Smooth surface
No it does not have to be smooth.
The rough surface is better than the smooth surface for the frictional force to act.
It is wrong to say that friction doesn't occur in smooth surface.. As ideally, no such surface exists, which has 0 value of friction. We can say that the magnitude of friction force is less in smooth surfaces as compared to that in rough surfaces. Friction opposes the motion of a body. When we go to the molecular level, we can see that the surface of a plane is not smooth but rough.. We cannot see that roughness through naked eyes. But the amount of roughness differs from object to object. The so called smooth surfaces have less roughness as compared to un-smooth surfaces. Hence, the magnitude of friction is LESS in smooth surfaces...
Here we are talking about the surface of the muscles..... Smooth muscles have smooth surface while striated muscles have rough surface.....
It is not smooth it has craters
Smooth
smooth surface
A basketball will roll faster on a smooth surface due to less friction compared to a rough surface. The rough surface creates more resistance, slowing down the ball's movement.
Smooth surface caries is on a surface that does not have pits, fissures. Usually on the front, back, or side of the tooth as opposed to the top where there are hills and valleys so to say. If the caries is on the crown part of the tooth it started on the enamel, but may have progressed down to the dentin which is the next surface under the enamel.
The physical property that describes how smooth the surface of an object is called "texture". Texture refers to the feel or appearance of a surface, whether it is rough, smooth, bumpy, or uneven.
