Question

1. Force of friction is directly proportional to
(a) size
(b) area
(c) weight
(d) all these factors of the moving body​

Answer 1

Answer:

answer of this question are (d) because size area weight are important for friction

Answer 2

Answer:

The Force of friction is directly proportional to (c) weight.

Explanation:

Friction exists as the force that resists motion when the surface of one object reaches contact with the surface of another. The mechanical benefit of a machine is facilitated by friction, or in other words, the ratio of output to input exists reduced because of friction.

The force that gravitation exercises upon a body are identical to the mass of the body times the local acceleration of gravity: generally assumed, in a region of constant gravitational acceleration, as a measure of mass.

Where the frictional force exists fk, the coefficient of friction stands μk and the normal reaction is N. Here the normal reaction of the body exists equivalent to the weight of the body. so the kinetic friction exists directly proportional to the normal reaction of the body.

Hence, the Force of friction is directly proportional to (c) weight.
