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.
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.
What happens if the net force on an object increases?
The amount of friction increases.
Pressing two objects together with more force friction?
Increases friction
How friction increases with weight?
yes, this is true when anyone increases our weight then no-one can't control oureself .( friction *weight).& increase the force .force is (torque*weight).hence friction increase with weight.

Does friction increases as rotation increases?
No. Friction is a function of Normal Force and the friction coefficient, nothing else.
How are friction and force related?
friction increases the amount of force necessary to do work
What happens if the net force on an object increases?
The amount of friction increases.
Pressing two objects together with more force friction?
Increases friction

How did the addition of more weight affect the friction?
When the weight increases the frictional force also increases:)
What determines the size of a frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
What determines the size of frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
What happened to the coefficients of friction as the weight increases?
Nothing. The coefficient of friction is constant, as it is dependent on the surfaces that are interacting. Normal force increases as an objects mass increases (Be careful with the word "weight", as it denotes the effect of gravity) in a constant gravitational field. This normal force is what causes an increase in friction.
