The force of kinetic friction does not depend on

Question

The force of kinetic friction does not depend on (A) the relative velocity of the two surfaces in contact. (B) nature of the surfaces in contact. (C) normal reaction on the moving body (D) all of the above

Tardigrade Admin · Accepted Answer

Kinetic friction is fk=μ kN, where μ k depends upon nature of surfaces in contact only.

Q. The force of kinetic friction does not depend on

the relative velocity of the two surfaces in contact.

nature of the surfaces in contact.

normal reaction on the moving body

all of the above

Kinetic friction is $f_{k} = μ_{k} N,$ where $μ_{k}$ depends upon nature of surfaces in contact only.
