buoyancy

the upward force that fluids (such as water) apply to any object placed in them.

the density of water (H20) is

1.0 g/cm3

if an object has a density greater than 1.0g/cm3, it will ________in water

sink

if an object has a density of less than 1.0g/cm3, it will f_________. a portion of the object that is equal to its d_________will be u________water.

float, density, underwater

if an object with a density of 0.9 we're cut in half, would it float? why?

yes, because it will be made of the same material
