$\Huge{\red{\underline{\textsf{Question\::-}}}}$
Write the types of motion?​

Answer 1

Answer:

$\bold{\underline{\boxed{\pink{\mathfrak{\sf{THERE \ ARE \ 7 \ TYPES \ OF \ MOTION }}}}}}$

$\bold{\underline{\boxed{\red{\sf{1. \ Rectilinier \ Motion}}}}}$ ${\implies}$ Motion which occurs along a straight line, is called as Rectilinier Motion.

Ex :

• Light from the sun.
• Light from the bulb

$\bold{\underline{\boxed{\red{\sf{2. \ Curvilinier \ Motion}}}}}$ ${\implies}$ Motion In Which the body travels along a curved path, is called as Curvilinear Motion.

Ex:

• Game of cricket
• Kicking of Football

$\bold{\underline{\boxed{\red{\sf{3. \ Translatory \ Motion}}}}}$${\implies}$ The body taking equal amount of the time to cover equal distance, This is called as Translatory Motion.

Ex :

• In the game of running race.
• Moving bus

$\bold{\underline{\boxed{\red{\sf{4. \ Rotatory\ Motion \ Or \ Circular \ Motion}}}}}$ ${\implies}$ If the body rotates on most in a circular path, it is called as Rotatory motion or Circular motion.

Ex:

• Merry-go-round
• Gaint wheel

$\bold{\underline{\boxed{\red{\sf{5. \ Oscillatory \ Motion}}}}}$ ${\implies}$ if a body move back and forth, then it is called as Oscillatory motion

Ex :

• Swigging
• Pendalum

$\bold{\underline{\boxed{\red{\sf{6. \ Vibrating \ Motion}}}}}$ ${\implies}$ if the rate of oscillation increases rapidly, it is called as Vibratory motion

Ex :

• Musical instruments like Guitar, drums, violin

$\bold{\underline{\boxed{\red{\sf{7. \ Periodic \ Motion}}}}}$ ${\implies}$ Body repeats its motion after regular or constant intervals of time, this motion is called as Periodic motion.

Ex :

• Hands of the clock
• Earth revolving around

Answer 2

➠ 'ʀᴇᴄᴛɪʟɪɴᴇᴀʀ ᴍᴏᴛɪᴏɴ' ᴏʀ 'ʟɪɴᴇᴀʀ ᴍᴏᴛɪᴏɴ' : The Simplest type of motion, along a straight line is known as (linear motion) / (Rectilinear motion)

For Example :--- Motion of a train on straight track, Falling of an apple from a tree, Straight March - past of soldiers in a parade, this all can be called as Examples of 'Rectilinear Motion'.

We realise that in all these cases, the objecs concerned are moving along a (nearly) straight path. We call all the such motions as 'Rectilinear' or simply as 'Linear Motion'.

➠ ᴄᴜʀᴠɪʟɪɴᴇᴀʀ ᴍᴏᴛɪᴏɴ : The motion which moves along a curve path. For Example :-- Throwing a stone in pond, it produces curve like structure in the pond, So we can realise that this type of motion are 'Curvilinear motion'.

➠ ᴜɴɪғᴏʀᴍ ᴍᴏᴛɪᴏɴ : When an object, moving along a straight path, covers equal distances in equal intervals of time, (howsoever small these time intervals may be) its Motion is called as 'Uniform motion'.

➠ ɴᴏɴ - ᴜɴɪғᴏʀᴍ ᴍᴏᴛɪᴏɴ : When an object (i) moving along a straight path, covers unequal distances in equal intervals of time or (ii) doesn't move along a straight path, its motion, is called as 'Non - Uniform Motion'.

➠ ʀᴏᴛᴀᴛᴏʀʏ ᴍᴏᴛɪᴏɴ : The motion which moves along a rotatory path. Example of this motion is 'Potter making a pot'. These type of motion are known as 'Rotatory Motion'.

➠ ᴏsᴄɪʟʟᴀᴛᴏʀʏ ᴍᴏᴛɪᴏɴ : The motion which moves along a oscillatory path. Example of these motion are (i) moving of pendulum. These type of motion are known as 'Oscillatory motion'.

★ When is an object to be in motion ?

An object is said to be in motion when, its position with respect to its immediate surroundings changes with time.

★ When is an object said to be in rest ?

When the position of an object with respect to its immediate surrounding does not changes with time it is said to be in rest with respect to its surrounding.

★ Justify that 'All motion is relative'.

It is, important to realise that all motion is relative. A given object may be regarded as being at rest by one observer and as being in motion by another observer. For example, two persons, sitting next to each other in a moving train, are at rest with respect to each other. However, they are both in motion with respect to a person standing outside on the platform.

Have you ever experienced that while sitting in a train, standing on the platform, you suddenly feel that your train has started moving. This happens, when another train on neighbouring track crosses your train. Thus, the decision about a given object's state of rest or motion depends very much on the observer and the surroundings chosen.
