Is it true that weight affects the amount of friction between the object and a surface?
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
True or false when an object rolls over a surface the kind of friction that occurs is called round friction?
false it is rolling friction
Air resistance is a type of friction True or False?
Air- resistance is basically a type of friction between an object and the air
Does rough surfaces exert greater friction?
Yes. Think about two steep hills. One is covered in ice (smooth). The other is covered in sandpaper (rough). The ice covered hill would be MUCH easier to slide down. Thus, the friction is much LESS, on a SMOOTH SURFACE. Then the opposite must be true, that friction is GREATER on a ROUGH SURFACE.
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 weight affects the amount of friction between the object and a surface?
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
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.

false it is rolling friction

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.
Air resistance is a type of friction True or False?
Air- resistance is basically a type of friction between an object and the air
Friction always makes the effiency of a machine less than 100 true or false?
True.
Does rough surfaces exert greater friction?
Yes. Think about two steep hills. One is covered in ice (smooth). The other is covered in sandpaper (rough). The ice covered hill would be MUCH easier to slide down. Thus, the friction is much LESS, on a SMOOTH SURFACE. Then the opposite must be true, that friction is GREATER on a ROUGH SURFACE.
True or false it is easier to use in line skates when surface is rough?
false of course it is too rough. it is better in smoother places
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
When two surfaces rub do the irregularities of one surface get caught on those of the other surface?
Yes, this is a true statement and causes friction.
