Question

define oscillatory motion , translatory motion

Answer 1

Translatory Motion

The motion of an object is said to be translatory if the position of the object is changing with respect to a fixed point or object. All the particles of a body excuting translatory motion move in the same direction traversing parallel paths.
Oscillatory Motion

Oscillatory motion is repetitive and fluctuates between two locations. The to and fro motion of an object about a fixed point is called oscillatory motion or vibratory motion.

Answer 2

Oscillation is the process of moving in a steady and uninterrupted way and oscillatory motion is the movement created by the process.

  Translatory motion is the movement in which all the particles in the body move through the same distance in the same time. There are two types of translatory motion- rectillenear and curvillenear motion.
