The motion of a body as a whole through a distance is
translatory
Explanation for correct option(s):-
Option (a):- translatory motion
When an object as a whole, moves from one place to another, it is termed translatory motion.
Explanation for incorrect option(s):-
Option (b):- circular motion
When an object moves in a circular path, the motion is known as circular motion.
Option (c):- oscillatory motion
When an object moves to-and-fro about a fixed point it is said to be in oscillation motion.
Option (d):- periodic motion
A repetitive motion that takes place at equal intervals of time is called periodic motion.
Thus, when an object as a whole, moves in a straight path, it is termed translatory motion. Hence option (a) is correct.
