Question

b. Define translatory motion, periodic motion and rotational motion.
​

Answer 1

Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.

Answer 2

Answer:

Translatory Motion: when an object ( like a car) move in the line in such a way that every point of the object move through the same distance in the same time its motion is called translatory motion.

Periodic Motion: A motion that repeat itself at regular intervals of time is called periodic motion.

Rotatory motion: When an object moves about a fixed axis without changing its position its motion is called rotatory motion.
