Yes, generally, smoother surfaces have less friction because there are fewer irregularities to hinder motion. Friction is caused by the microscopic bumps and ridges on surfaces rubbing against each other, so a smoother surface allows for less resistance to movement.
True. Lubricants reduce friction by forming a thin layer between moving surfaces, which helps to replace sliding friction with fluid friction. This allows for smoother movement and decreased wear on the surfaces in contact.
Carpet has more friction. In my science class we did an experiment and proved this true.
True, friction is a force that opposes the motion of an object when it is in contact with another surface. Friction can cause the object to slow down or stop moving.
False. The type of friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is caused by the deformation of the object and surface at the point of contact, which generates resistance that opposes the motion of the object.
True. Friction is the force that resists motion when the surface of one object comes in contact with the surface of another

Yes it is true.
false it is rolling friction
True, that is a source of friction.
True, that is a source of friction.
No, it is not true that the Earth is smoother than a cue ball. The Earth's surface has mountains, valleys, and other features that make it rougher than a cue ball.

No, weight does not directly affect the amount of friction between an object and a surface. The factors that affect friction are the nature of the surfaces in contact and the force pushing them together. The normal force, which is perpendicular to the surface, is what influences the frictional force, not the weight of the object.
