Question

If the density of an object is less than the density of water, what will the object do? (Points: 3)
float

sink

bob up and down

move forward

Answer 1

Answer 2

It will bob and down, for example oil, oil is less dense than water thus, it floats on top of water.

Answer 3

why would it bob up and down? I think that only happens when the density of the object is equal to the density of the water

Answer 4

I'm imagining that there are no waves in the water

Answer 5

yeah i thought float but not sure

Answer 6

Well i'm assuming when they say bobs up and down, they mean the object floats.

Answer 7

either way it bobs up and down because its most closest to being floating. cuz the object density is less than water.

Answer 8

bobbing up and down is like it is between floating and sinking. So it's like it is struggling to float. That's how I view it.

Answer 9

@jim_thompson5910 so it would float?

Answer 10

either way it is floating, its no sinking.

Answer 11

Thanks

Answer 12

Its probably bobbing up and down because the object density, is really close to being the same as the density of water, but still a little less.
