According to the laws of mechanics. Friction is defined as the force resisting motion. Whenever there is motion there is friction opposing it. The frictional resistance of a surface is given by an unit less index called coefficient of friction. This depends upon the roughness of the surface. Friction = coefficient * normal reaction Thus, from the formula it is seen that friction is directly proportional to normal reaction and coefficient of friction. Normal reaction is nothing but the the perpendicular reaction provided to a body by a surface as a result of all the perpendicular forces acting on the surface due to the body. for example, consider a block of wood on a table. Weight of the body acts downwards perpendicular to the surface of the table.Thus here the table will apply an equal and opposite force on the block(Newton's third law). This force will be perpendicular to the both the block and the table surface.Thus it is known as the normal reaction. As is seen that every object exerts it weight upon the surface it is placed on. Weight = mass* g. Where g = acceleration due to gravity(=9.81 for earth surface) Thus increase in mass increases normal reaction. Hence increasing friction. "FRICTION VARIES DIRECTLY WITH MASS"

∙ 12y agofriction coefficient, 1kg mass takes 0.5kg force to push horizontally,
coefficient = 0.5/1 = 0.5
actually there are two , static and sliding, static or breakaway friction is usually greater, though the equation holds true for both

∙ 12y agoThe force needed to move an object depends e.g. on the mass of the object. When the mass increases, the downward force on the object increases as well (9.81N/kg), thereby causing more friction.

How does friction affect interia?
Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.
How does the weight of an object affect friction?
The frictional force(f) = μ *mg for horizontal motion, where μ = coefficient of friction, m = mass of the object, g = acceleration due to gravity. Hence friction depends upon the weight of the object.
Factors that affect the amount of friction?
1.nature of the substance and the surface (roughness or smoothness). 2.mass of the object.
How does weight and mass affect friction?
Well weight and mass are proportional... But mass affects friction because the higher your mass the higher your friction.
What are the two factors that determine frictional force?
two variables are : the surface type and the mass of the object. So the more mass an object has the less friction it has. The less mass an object has, the more fiction it has.
Does the mass of an object affect friction-?
Yes Friction=Reaction force x COF Reaction force = mass x gravity So Friction=mass x gravity x COF ^ Change the mass, change the friction
How does gravity friction and mass affect the motion of an object?
Sin no
How does friction affect interia?
Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.
What are factors that affect an object's kinetic energy?
The factors affecting kinetic energy are mass and velocity.
What two factors affect the motion of an object sliding downhill?
Mass (gravity) & friction!
What effect does the mass of an object have on acceleration or deceleration of an object when an unbalanced force acts on it?
this is a tricky 1 because the mass itself does not affect it, but rather the friction of the plane it is moving on and the momentum (which does factor in mass) if no friction exists, then it is purely the momentum. momentum = mass x velocity
How does the weight of an object affect friction?
The frictional force(f) = μ *mg for horizontal motion, where μ = coefficient of friction, m = mass of the object, g = acceleration due to gravity. Hence friction depends upon the weight of the object.
Factors that affect the amount of friction?
1.nature of the substance and the surface (roughness or smoothness). 2.mass of the object.
Does mass effect friction?
mass effects friction by making the object go slower as mass increases
How does weight and mass affect friction?
Well weight and mass are proportional... But mass affects friction because the higher your mass the higher your friction.
What are the two factors that determine frictional force?
two variables are : the surface type and the mass of the object. So the more mass an object has the less friction it has. The less mass an object has, the more fiction it has.
Is friction affected by the amount of surface that is touching?
No: this is a common misconception Friction= Normal force* Coefficient of friction where Normal force= Mass* Acceleration due to gravity* Cos(angle of surface) and the coefficient of friction is an intrinsic property of the surface Therefore, only the mass of the object and the surface composition affect friction
