Motion and Types of Motion


1.) Identify the types of motion.

a.) Movement of the earth around the sun: Circular and periodic motion.

b.) Movement of a ceiling fan : Circular motion.

c.)  A meteor falling from the sky : Non – uniform linear motion.

d.) A rocket launched from the ground : Non – uniform linear motion.

e.) A fish swimming in water: Random motion.

f.) The plucked string of a sitar: Oscillatory motion .

2.) Fill in the blanks.

a.) If a ball is released from the terrace of a building, it comes down in non uniform linear motion. On the other hand, it reaches the ground in non- linear 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 non – uniform linear motion .

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

d.) Children sitting in a rotating giant wheel have non -uniform circular motion,  while those sitting in a merry – go – round have auniform circular motion.

(Linear , non – linear , circular, uniform linear, non – uniform linear , uniform circular, non – uniform circular, random)

3.) How are we different?

a.) Oscillatory motion and linear motion.

Difference between oscillatory motion and linear motion

Oscillatory motion

i) Oscillatory motion may be defined as the back and forth motion of an object from it’s fixed

ii) The wings of a bird is one such example.

Linear motion

i) When an object proceeds from one place to another place following a straight line is known as linear motion.

ii) As for instance, any vehicle travelling in a straight line or following the same direction. This motion of any particular object is termed as linear motion.

b.) Linear motion and random motion

Difference between linear motion and random motion

Linear motion

i) When an object proceeds from one place to another place following a straight line is known as linear motion.

ii) As for example, a stone falling from a specific height.

Random motion

i) Random motion may be defined as the kind of motion in which , the speed and direction of motion of any particular object changes in a continuous manner. In short , when there is no specific direction to it’s motion .

ii) As for example, a butterfly flying constantly from one flower to another flower.

4.) Explain in your own words , giving one example each.

a.) Linear motion – Linear motion as the name indicates, refers to the movement of an object from one position to another position following a straight line.

As per example , a car running at a continuous speed.

b.) Oscillatory motion – Oscillatory motion refers to the kind of motion in which the object proceeds from one end to another end  in a continuous manner from it’s mean point.

The movement of the pendulum clock falls under the category of oscillatory motion.

c.) Circular motion – Circular motion can be defined as the type of motion in which an object proceeds from one position to another position in such a manner that it maintains a constant distance from its fixed point. In short, circular motion as the name suggests, refers to the motion of an object that moves along a circular track.

The blades of a fan moving in a circular manner is one of the perfect example of circular motion.

d.) Random motion – An object is said to have random motion, if the speed and direction of motion of an object changes in a constant manner. In other words, when the motion lacks any specific direction then it is termed as random motion.

Children running in a playground is one of the example that portrays random motion.

e.) Periodic motion – Periodic motion refers to a type of motion in which the object passes in such a manner that there is repetition of its motion after a fixed period of time.

Rocking chair is one of the relevant example of periodic motion.

5.) Answer the following questions in your own words.

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

Random motion is the type of motion that is seen in birds flying in the sky.  Birds flying in the sky mainly depicts random motion because their speed and direction of motion changes constantly.

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

We experience various types of motion, while riding a bicycle on a road. The wheels of a bicycle depicts both rotatory and rectilinear motion. The wheels of a bicycle rotates in a constant manner, so as a result of which it is said to possess rotatory motion. Simultaneously, the wheels of a bicycle also portrays rectilinear motion because the rotating wheel also enables the bicycle to move in a forward direction.The pedals of a bicycle shows circular motion because as they are tied to the chain, so they are unable to move in any path of direction apart from moving in a circular manner.

6.) Complete the puzzle using words for types of motion :

1) a spring is stretched and one end is released

2) a minute hand

3) a see saw

4-5 ) children in a march past

6) a stone rolling down a hillside.
