If it is perfectly smooth then only sliding friction.
The rough surface is better than the smooth surface for the frictional force to act.
If the surface is smooth then it is almost frictionless. Hence the body will continue to move with constant velocity. However the object continues in a circular path and the weight is thus the centripetal force. It is assumed that the surface is very large)
No, the frictional force does not depend on the area of surface contact. It is primarily determined by the nature of the surfaces in contact and the normal force pressing the surfaces together. The coefficient of friction between the surfaces also plays a role in determining the magnitude of the frictional force.
You can demonstrate that frictional force depends on the nature of the surfaces in contact by conducting an experiment where you measure the frictional force between different surfaces. By varying the types of surfaces (e.g., smooth versus rough), you can observe how the frictional force changes accordingly. The coefficient of friction, which quantifies this relationship, will be different for each pair of surfaces, highlighting the influence of surface nature on frictional force.
More friction is produced on a hard surface than on a smooth surface it takes more force and brute strength to push something heavy on a rough surface, because it falls in the cracks. On a smooth surface you are just sliding across a surface.
A rough surface with a lot of friction, like sandpaper or a rubber surface, would create the largest frictional force to resist the motion of a wooden block. Smooth surfaces have less friction and would not resist the motion as much.
Frictional force
Frictional force is the force that opposes motion between two surfaces.
Yes, the frictional force depends on the type of surfaces in contact. It is influenced by factors such as the roughness, texture, and material composition of the surfaces. Smooth surfaces typically have lower friction compared to rough surfaces due to less interlocking of surface asperities.
Yes, the force of static friction is also acting between the soles of your shoes and the road surface to help propel you forward while running. This force allows you to push off the ground and move in the direction you want.
The rougher then surface the greater the frictional force. When a surface is rough and you put friction to it, it creates sparks while smooth surfaces when friction is added causes a slight stactic shock.
