Question

I have usually seen that while stirring the glass containing light entities like teas leaves, they gather in the middle. What leads to such a phenomenon?​

Answer 1

Answer:

Inertia is the phenomenon wherein a mass tends to maintain its current state of motion. This includes changes in the velocity, direction, or momentum of the object.

Answer 2

Answer:

1. By stirring the glass containing tea leaves, this introduces work on the glass container.
2. This work is translated into a rotary motion on the water.
3. This rotary motion causes the water at the outer edges of the glass to go up and form a depression in the middle of the glass.
4. This creates a pressure difference between the outer edge of the glass having high pressure and the low pressure in the middle.
5. Since the natural movement of water is from higher pressure to lower pressure, this causes the tea leaves suspended in the water to gather in the middle.
