Answer 1

Answer:

oscillatory or periodic

Answer 2

Required Answer:-

${\underline {\boxed {\Large {\rm { a) \: Periodic \: motion \: \checkmark } }}}}$

Motion of a swing is :-

• Periodic motion ✔
• Vibratory motion
• Random motion
• Straight line motion

➜ Motion of a swing is a Periodic motion.

Explanation :

${\underline {\boxed {\small {\bf { Option\: a) } }}}}$

» Motion of a swing is an example of Periodic motion because it shows motion, which is repeated in equal intervals of time. ✔

${\underline {\boxed {\small {\bf { Option\: b) } }}}}$

» Swing can't be an example of vibratory motion as because oscillation only takes place at a rapid time. So, for the movement of a swing, it requires equal intervals of time.

${\underline {\boxed {\small {\bf { Option\: c) } }}}}$

» Random motion is a motion of movement in different directions with no fixed path. Hence, a swing can't be categorized as an example of random motion.

${\underline {\boxed {\small {\bf { Option\: d) } }}}}$

» Straight line motion is also known as rectilinear motion, It is a motion in which a body moves in a straight path. Therefore, swing can't be an example of rectilinear motion.

Hence, Option A) is correct. ✔
