What else can I help you with?
Is rough surface better or smooth surface?
The rough surface is better than the smooth surface for the frictional force to act.
When and object slides over a smooth horizontal surface how does the force of friction depend on the force of gravity on the object?
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)
Does the frictional force depend on the area of surface contact?
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.
How can you show that frictional force depends on nature of surface in contact?
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.
How does frictional force vary with change in roughness of the surfaces?
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.
What surface would have the largest frictional force to resist the motion of a wooden block?
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.
What is the force that oppose motion between surface?
Frictional force
What frictional force?
Frictional force is the force that opposes motion between two surfaces.
Does then frictional force depend on the type of surfaces in contact?
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.
When you are running on a road you are acted upon by frictional force of the road.Is there another force of friction acting on you?
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.
How does the roughness of a surface effect friction?
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.
