Motion and Types of Motion Exercise question Solutions :

Question no – (1)

Answer :

(a) Movement of the earth around the sun :

= Here we observed two type of motion one is circular motion and other one is periodic motion.

(b) Movement of a ceiling fan :

= Movement of a ceiling fan had two type of motion (i) Oscillator motion and (ii) Circular motion.

(c) A meteor falling from the sky :

= A meteor falling from the sky have a linear motion.

(d) A rocket launched from the ground :

= A rocket launched from the ground – here we see Linear motion.

(e) A fish swimming in water :

= A fish swimming in water here we see Random motion.

(f) The plucked string of a sitar :

= The plucked string of a sitar have Oscillatory motion.

Question no – (2)

Answer :

(a) If a ball is released from the terrace of a building it comes down in uniform linear motion. On the other hand it reaches the ground in random motion if it is thrown with force away from the terrace in a direction parallel to the terrace.

(b) The motion of an aeroplane on the runway before take off is linear.

(c) The kite looking for its prey flies with Circular motion in the sky.

(d) Children sitting in a rotating giant wheel have Uniform circular motion, while those sitting in a merry-go-round have a on-uniform circular motion.

Question no – (3)

Answer :

(a) Differences between Oscillatory motion and linear motion as follows :

Oscillatory motion :

It is the type of non-linear motion in which the objects never move in a straight line.
The objects which shows oscillatory motion they come back at same position again and again.
For example- ceiling fan ,merry –go-round, giant wheel etc

Linear motion :

It is the linear motion in which objects moves in a linear motion.
The objects shows this type of motion they not come back again and again they go forward from original position.
For examples- running train.

(b) The differences between Linear motion and random motion are discussed below :

Linear motion :

In the linear motion the objects are travelled in a straight line with same direction.
It shows same direction
For example- running train

Random motion :

In a random motion the objects are not travel in a straight line they are change their direction.
It shows different direction
For example- flying butterfly.

(c) The difference between Random motion and oscillatory motion are as follows:

Random motion :

The motion in which direction are changes or travels in different direction is known as random motion.
It is a non-linear motion does not have particular direction.
For example- flying birds or butterfly

Oscillatory motion :

The motion in which the objects goes forward and come again backward direction is known as an oscillatory motion.
It is non-linear motion but have particular direction.
For example- pendulum of a clock.

Question no – (4)

Answer :

(a) Linear Motion :

It is the type of motion in which objects are moving in a straight line or in the same direction is known as linear motion. There are two types of linear motions uniform linear motion and non- uniform linear motion. In the uniform linear motion the objects are travelled in a straight line in unit time. In the non-uniform motion is in a straight line but not in unit time the objects are changes.

The motion of running train – is a example of linear motion.

(b) Oscillatory motion :

The motion of a object moving in back and froth direction is known as oscillatory motion. The objects are moving in forward direction and again back ward direction and this happens again and again. If the oscillation motion is completed in a given time then it is known as periodic motion.

The movement of pendulum in a clock is a example of Oscillatory motion.

(c) Circulatory motion :

The motion of an object in a circular path is known as circulatory motion. If it is completed in a given period of time then it is known as periodic motion. We can see very examples of circulatory motions like the motion of clock shows circular and periodic motion.

The motion of cycle pedal is a example of Circular motion.

(d) Random motion :

The motion of an object is not fix for any direction or changes its speed and direction is known as random motion

The motion of an flying butterfly is a great example of Random motion.

(e) Periodic motion :

The motion in which objects pass through a path again and again in a particular time is known as periodic motion. In this motion objects rotate in a particular time.

A merry-go-round completes its round in a specific timing; therefore it is also known as periodic motion.

Question no – (5)

Answer :

(a) There are different types of birds are flying in the sky some bird’s shows random motion like crow shows random motion. Some are shows linear motion they fly in a straight direction, some are show circular motion like kite .these are different types are motion are shown by birds when they are flying in the sky.

Question no – (6)

Answer :

(a) If a spring is stretched and one end is released – here we observe the oscillatory motion.

(b) We see circular motion on a minute hand.

(c) On a see saw we see Periodic motion.

(d) 4 – 5 children in a march past – here we see uniform ,linear motion

(e) On a stone rolling down a hillside – Here we see Random motion.
