THE DIFFERENCE BETWEEN CIRCULAR MOTION AND ROTATIONAL MOTION

In CIRCULAR MOTION, both the position of the object in motion and its direction are changing.
For example, you draw a wide circle ⭕ on the ground and you are moving along the circle.
You will observe that ur body left ur initial position to another position.
And also, u are changing direction.
Using a circle and a compass 🧭, 0° is East, 90° is North, 180° is West, 270° is South and 360°(complete circle) is East again.
While moving round this circle, u start from East and move curly to North, from North to West and from West back to East.
You can see that u are changing direction.
And u also changed ur position -- that's CIRCULAR MOTION.
Another example of this is the movement of a car round a roundabout.

In ROTATIONAL MOTION, only ur direction is changing.
U sit on a chair that can swing 360°....U are turning and changing direction, from East to North to West and to South without leaving that same position.
Another example of this is the movement of a ceiling fan.

In the electromagnetic spectrum, ROYGBIV are the visible light to we human beings.

R is Red ♥️ colour
O is Orange 🧡
Y is Yellow 💛
G is Green 💚
B is Blue 💙
I is Indigo
V is Violet

Red has the longest wavelength
Violet has the shortest wavelength

According to Wein's displacement law, the lower the wavelength, the higher the temperature and vise versa.

What that means in essence is that, Red colour that has the longest wavelength has the lowest temperature and Violet colour that has the shortest wavelength has the highest temperature.

Let's talk about fire 🔥

Wein's displacement law is applicable to fire as well

Red ♥️ coloured fire has the lowest temperature.
Orange 🧡 coloured fire has a temperature higher than Red coloured fire.
Yellow 🟡 coloured fire has a temperature higher than Orange coloured fire 🔥
Green 💚 coloured fire has a temperature higher than Yellow coloured fire 🔥
Blue 🔵 coloured fire has a temperature higher than Green coloured fire 🔥

That means, the hottest fire among these 5 fires is the blue 💙 coloured fire
