Answer:
(a) Kinetic friction depends on velocity of the body.
a)false
Friction force depends on the nature of the materials in contact and their coatings for both static and kinetic (moving) conditions and is independent of velocity of body.
(b) Static friction is independent of area of contract.
b)true
(c) Kinetic friction is directly proportional to normal reaction.
c)true
