Homework Statement

What are the two physics ideas of spinning a bucket of water in a vertical circle? would it be centripetal and centrifugal force?

Relevant Equations

F = mac = (mv2 / r)

F = mac = (mv2 / r)

The question is rather vague. You would not use both concepts to analyse it, you wouid use one or the other. Please quote the question word for word as given to you.

Oh sorry, the exact question word for word is: What are two or more physics ideas which are relevant to spinning a bucket of water in a vertical circle?

Thank you.

Ok.
Certainly centripetal force. I would not mention centrifugal for the reason I gave.
Vertical implies a certain other force should be relevant, but not sure that it is an 'idea' in this sense.
Might be able to work a conservation law into it.
So far, it could be an empty bucket. How can you bring the water into it?

I would think that an idea would be what relates this other vertical force to the centripetal force so that the water can go around the circle without spilling.

Don't guess. Do some internet research. Watch videos of buckets spinning in vertical circles. They come with explanations that should give you some ideas.
