Question

how can it happen that with fetching water from well we pull the rope in downward direction and bucket moves in upward direction?​

Answer 1

Answer:

this is due to force of gravity or gravitational force or pull

Answer 2

Answer:

Explanation:

The length of the rope is finite.

So, if we pull the rope downwards then the rope will move down in the direction of applied force .

So the rope part which is attached to bucket becomes less . As the rope part in the hand becomes more .

So the bucket rises up the pulley.

Here assume that spring constant value is negligible due to strong fibres in rope.

I hope you understand
