1. Place an aluminum block in the water. Record the densities of the block and liquid:
Block volume: _______________
block density: _______2750kg/m^3________
What are the magnitudes of the gravitational force and buoyancy force on the block?
What is the apparent weight of the block in the water?
liquid density: ___1000 kg/m^3____________
gravitational force: ___26950 N ↓____________
buoyancy force: ______9800 N _↑________
apparent weight: _______________
Given the volume of the block and the densities of the block and fluid, show mathematically why these magnitudes make sense.
The block density greatly exceeds the liquid density, the buoyancy force is not enough to over come the gravitational force, and the block sinks in the liquid.
