The mass of an object is constant. The force of friction is a force that resists motion. When an object moves on a surface, the force of friction opposes the motion. Depending on the properties of the surface, the force of friction will change. This difference in frictional properties is demonstrated by 'mu' a greek symbol. Force of friction = mu x Force of gravity = mu x mass x acceleration due to gravity.Therefore, as the mass of an object increases, so does the force of friction that acts upon it while in motion. mu is a constant for a specific surface, so it is a value you have to be given in some cases in order to calculate the force of friction. Comparing ice and ashphalt, ice would have a lower friction coefficient, mu, than ashphalt would and therefore, the force of friction on any given mass moved on either surface would be greater on an ashphalt surface.

How are friction and mass of an object related?
force of friction= coefficient of friction x force of normal force of normal is mass x whatever force that is acting on it (usually gravity)
How is force and friction related?
The Force of friction is equal to the coefficient of friction times the normal force. Since normal force is equal to mass times the acceleration of gravity (9.8 m/s2), the force of friction is directly proportional to the mass.
Will frictional force depends on mass and density?
Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity.
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
Why does a larger mass cause more friction?
Friction force (f) is the normal force by the surface on the object multiplied by the coefficient of friction.f = N1S u

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
What is the relationship between mass and force of sliding friction?
they are directly proportional, the greater the mass, the greater the sliding friction
Will frictional force depends on mass and density?
Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
What are examples of force?
- Gravity/weight - Air resistance/drag/friction - Centrapetal force
What is the force that opposes motion?
Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
How do you apply friction?
Friction acts in the opposite direction that the object is moving or trying to move. The force of friction is calculated by multiplying the normal force of the object, usually mass times gravity, by the coefficient of friction.
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
What is the independent controlled and dependent variable of how mass effects the force of friction?
The independent variable is mass. The dependent variable is the frictional force.
Why does a larger mass cause more friction?
Friction force (f) is the normal force by the surface on the object multiplied by the coefficient of friction.f = N1S u
