Studii de caz
- Predict whether an object will sink or float when placed in a liquid, given densities of the object and liquid
- Apply the definition of density to both liquids and solids
- Relate the buoyant force on an object to the weight of liquid it displaces
- Describe how the buoyant force is related to an object's relative density to the fluid
- Predict the weight of a completely or partially submerged object of known mass and volume
- Describe the forces that act on a completely or partially submerged object
- Explain how an object that is more dense than water can be kept afloat by placing it on an object that is less dense than water
