Question

class 9 motion notes chapter 8
please give me notes some one​

Answer 1

Answer:

Motion= movement.

Rest = Rest In position.

[Types of motion. ]

1. Uniform motion

2. Non uniform motion.

3. Oscillatory motion.

4. Rotatory motion.

5. Translatory motion have two ✌types

: 1.Rectilinear motion.

2.curvilinear motion.

now.........

Uniform motion: If an object travels equal distance in equal intervals of time is known as uniform motion.

Non uniform motion: If an object travels unequal distance of time is known as non uniform motion.

Oscillatory motion : The two and fro motion of an object is known as oscillatory motion.

Rotatory motion: If an object rotates it's selfish called as rotatory motion

Translators motion : If an object travels in a straight path is known as translatory motion.

Rectilinear motion : If an object travels in a straight line of path is known as Rectilinear translatory motion.

Curvilinear translatory motion : If an object travels in curved path is called as curvilinear motion.

Fast : If an object in fast motion.

slow : If an object in slow motion.

What is relative?

= In general comparable is scientifically known as relative. It shows North, south, east, west, right, left, up, down etc...

ex.. A girl is swinging on a swing. According to the swing the girl is in rest position. According to the surrounding she is in motion.

Distance / Displacement

.. Distance is the actual length of the paths travelled by an object between two ✌points in a given intervals of time⌚.

... A path traveled by an object is known as distance.

... The shortest distance traveled by an object in a specified direction is called Displacement.

and other I will tell u afterwards
