__speed__: a measure of how fast something is moving. The rate at which distance is covered (m/s)

__velocity__: speed in a given direction (m/s)

V = volume of fluid displaced

m = mass of the displaced fluid

For an object that is submerged, F

_{b}is equal to the pressure difference between the pressure at the top of the object and bottom of the object multiplied by the area of the surface of the bottom or top (pg 80)

#### Words From Our Students

"StudyBlue is great for studying. I love the study guides, flashcards, and quizzes. So extremely helpful for all of my classes!"

Alice, Arizona State University

"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"

Tim, University of Florida

"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"

Jennifer, Rutgers University

"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"

Justin, LSU
