Sinking, Floating and Suspending Investigation:
Test Your Understanding (student handout continued)
1. Which blocks floated and which sank? Did any suspend? Why do you think the blocks behaved as they
did? Make sure to mention the density of the blocks in your answer.
2. Draw a FBD for a floating block. What force is holding the blocks up? What is the magnitude
of this force?
3. Draw a FBD for the floating oblock being forced underwater. What is the magnitude of the force needed
to push a block underwater?
4. Draw an FBD for a sunk block.
