Answer 1

Answer:

(a) Birds flying in the sky have random motion as their direction of motion and speed continuously changes. (b) While riding a bicycle on a road, following types of motion can be seen: The wheels of the bicycle are in uniform or non-uniform circular.

Answer 2

Required Answer:-

(a) Which types of motion are seen in birds flying in the sky?

• The type of motion seen in birds flying in the sky is $\boxed{ \rm{Random \: motion }}$.

Explanation:

$\bullet$ The type of motion is Random motion as because when the birds fly in the sky, then they don't move in any fixed path, they are mostly seen flying in all the directions. Also, it's seems to be the combination of different types of motion.

Therefore, Random motion is the most appropriate answer for the motion of a flying bird. $\checkmark$

(b) Write in detail about your experience of various types of motion while riding a bicycle on a road.

Firstly let's know about various types of motion :

1. Translatory motion
2. Rotational motion
3. Circular motion
4. Periodic motion
5. Non-periodic motion
6. Random motion
7. Vibratory motion

$\dag \: { \underline{ \bf{According \: to \: the \: question}}}$

1. Translatory motion ::

• Well, if I would have been riding on a bicycle with translatory motion, then all its parts will move in the same distance in the given time. We can also state that all its parts move simultaneously.

2. Rotational motion ::

• If I would have been riding on a bicycle with rotational motion, then the bicycle will move at its fixed axis without changing the position. Let's take an example to make this statement more clear : 'Merry-go-round'.

3. Circular motion ::

• If I would have been riding on a bicycle with circular motion, then the bicycle will move around a circular path such as the way that its position will keep changing with time.

4. Periodic motion ::

• If I would have been riding on a bicycle with periodic motion, then the bicycle will repeat its motion after fixed intervals of time.

5. Non-periodic motion ::

• If I would have been riding on a bicycle with non-periodic motion, then the bicycle will not repeat its motion after same intervals of time.

6. Random motion ::

• If I would have been riding on a bicycle with random motion, then the bicycle will move in different directions with no fixed path.

7. Vibratory motion ::

• In this type of motion, the bicycle will take place at rapid time.
