Negative buoyancy Study guides, Class notes & Summaries

What will the buoyancy of an object be (positive, neutral, or negative) if it displaces an amount of water: a. more than its own weight? b. less than its own weight? c. equal to its own weight? - a. positive b. negative c. neutral How does the buoyancy of an object differ in fresh water compared to salt water. - Because salt water weighs more than fresh water, it causes more buoyancy (more upward force) What is the relationship between increasing and decreasing depth and water press...
