Answer 1

OK
A screw undergoes two types of motion at the same time.
one is rotatory motion as srew rotates about its own axis and second one is translatory motion or linear motion bcoz screw moves forward in a straight line at the same time
Random motion also know as Brownian motion .Brownian motion is a random motion of particles suspended in a fluid resulting from their collision with the quick atoms or molecules in the gas or liquid. eg : a fish swimming in water ,a flying butter fly,a bird flying in the sky
