What is the effect of friction on mass?
1 Answer
Friction can't affect mass of a substance(considering for a substance whose mass doesn't change with time),rather it is the mass of an object which can affect friction variously.
Let's take some example to understand the situation.
Suppose a block of mass
So,for
So,higher the mass of the object,higher will be the frictional force.
Now,suppose,you are pushing a block of mass
So,here frictional force acting is
Which tends to balance the weight of the block,
So,
Or,
But,here you can see that mass of the block has no effect on the frictional force rather it depends on how harder you apply the force
So,only in case when normal reaction is directly proportional to the weight,only in that case mass plays an important role in the determination of frictional force that can act.
