Does sand paper reduce friction?
sand paper increases friction, that is to say that it is harder to slide something on sand paper than it is on a smooth surface.
Does sand reduce friction?
No, sand does not reduce friction but increase friction.
What are the factors which affect the force of friction?
Friction equals the coefficient of friction times the normal force. Friction increases as the roughness of the materials increases. It also increases as the force pushing the materials together increases.
Reducing friction in a machine increases or decreases?
Deceasing friction increases efficiency and reduces heat loss.
Does oil increases friction?
No.

Does friction increases as rotation increases?
No. Friction is a function of Normal Force and the friction coefficient, nothing else.
What is a feature of a car that increases friction?
the front boot of the car increases the friction on the car
Which has most friction - oil water or sand?
Sand.
Reducing friction in a machine increases or decreases?
Deceasing friction increases efficiency and reduces heat loss.
Does oil increases friction?
No.
Investigate-how friction increases with increase of size of an object?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
How friction increased?
With increased surface areas in contact, friction increases.
If sand is rubbed together what is the source of the energy which heats the sand?
Friction.
What happens if the net force on an object increases?
The amount of friction increases.
