**PROBLEM SOLVING**

**11 interactive problems with hints and detailed solutions.**

**KEY ITEMS:**

**• Most misunderstandings in this topic have to do with the buoyant force. Students tend to believe that it depends on the mass of the object. The buoyant force is the weight of the fluid that would occupy the same volume as the object, i.e. it is equal to the weight of the displaced fluid.**

**• Also, students often think that the buoyant force increases with depth. They confuse pressure with the buoyant force. **

**• Remind the students that Bernoulli's principle is just a statement of conservation of energy.**
