For example : If you run or walk your all

body parts also move alongwith you
through the same distance in the same
me. Some other examples of transla-

v Rotatory Mo on : Mo on of a body at a
fixed point is called rotatory mo on.

Example : Spinning of a top.

Most of the moving objects around us,
move translatory.
Translatory mo on are of two types!
