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"

How does the mass of sliding object affect friction?

The mass of a sliding object does not directly affect friction. Friction is primarily influenced by the nature of the surfaces in contact and the normal force pressing them together. However, in some cases, a heavier object may increase the normal force, which in turn can increase the friction force.


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 are friction and mass of an object related?

Friction is directly proportional to the mass of an object. As the mass of an object increases, so does the friction between the object and the surface it is moving across. This is because a heavier object has more contact with the surface, resulting in increased friction.


How can one determine the friction force when given the mass and acceleration of an object?

To determine the friction force when given the mass and acceleration of an object, you can use the formula: friction force mass x acceleration. This formula helps calculate the force resisting the motion of the object due to friction.


How do you calculate the friction force when given the mass and acceleration of an object?

To calculate the friction force on an object, you can use the formula: Friction force mass x acceleration. This formula helps determine the force resisting the object's motion due to friction.

How does weight and mass affect friction?

Weight affects friction by increasing the force pressing the surfaces together, resulting in more friction. Mass does not directly affect friction, but it influences the normal force, which in turn affects friction. Generally, higher weight or mass leads to higher friction.


What is the Physical concept of Force Friction and Mass?

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.
