What else can I help you with?
What True or false lubricants reduce friction by replacing sliding friction with fluid friction?
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.
What does have more friction sandpaper or carpet?
Carpet has more friction. In my science class we did an experiment and proved this true.
Is it true or false that the motion of an object is affected by friction?
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.
True or false when an object rolls over a surface the kind of friction that occurs is called round friction?
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.
Analyze the following sentences. Write true if the statement is correct or false if it's not.1. Friction is the force that is present whenever to surfaces are in contact?
True. Friction is the force that resists motion when the surface of one object comes in contact with the surface of another

Is it true that surface currents in the ocean develop from the friction between the ocean and the wind that blows across its surface?
Yes it is true.
When an object rolls over a surface the kind of friction that occurred is called round friction True or false?
false it is rolling friction
True or false when two surfaces rub the irregularities of one surface get caught on those of the other surface?
True, that is a source of friction.
When two surfaces rub the irregularities of one surface get caught on those of the other surface true or false?
True, that is a source of friction.
Is it true that the Earth is smoother than a cue ball?
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.

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.

Friction always makes the effiency of a machine less than 100 true or false?
True.

True. Friction is the force that resists motion when the surface of one object comes in contact with the surface of another
Is it true that weight affects the amount of friction between the object and a surface?
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.
