Answer 1

Answer:

Hey mate....

Here is your answer:

1] rotatory and translatory motion.

2] vibratory motion.

3] rotatory motion mean circulatory.

4] circulatory motion.

5] aa oscillationit is a particular kind of motion in which an object repeat the same movement over and over. it is easy to see that a child on a swing and the pendulum on a grandfather clock both oscillate when they moved back and forth along an Arc.

so it's periodic motion .

I hope it helps you.....

peace ✌
