The buoyant force of water on the object reduces the weight of the object In this experiment you will determine and compare the buoyant force on an object and the weight of the water pushed aside displaced by the object for three objects The Greek m Buoyant Force. Buoyant force is the upward force that fluids exert on all matter. . A great example is how a rubber duck floats in a bath tub. . Buoyant Force is Caused by Differences in Fluid Pressure. Fluids are a collection of randomly arranged molecules held together by . weak . cohesive forces. This is unlike crystals (solids) which arrange orderly on a lattice). Pressure, Pascal’s law.

Formula = Density = mass/volume. . = g/mL or g/cm. 3. . *How tightly packed the atoms are. . 2. By comparing densities you can predict whether an object will float or sink in a fluid. An object that is more dense will sink, an object less dense will float.. Unit 2. Forces. A . force. is a push or pull. .. When forces are . balanced. matter is . still. ..

What affects the pressure of a liquid?. Gravity. The density of the liquid . The depth of the liquid. Pressure. Remember when I told you that pressure increased when you went farther down in the water… Well how does pressure relate to depth if pressure is force divided by area…. NASA North . Dakota Space Grant Consortium. Deep . Sea Diver. Goal: . Design and Build a Neutrally Buoyant Object. What does it mean to be neutrally buoyant?. Balancing act between forces. Densities are equal. 11.2 . Floating and Sinking. Buoyancy= the ability to float. buoyant force . – acts in a direction opposite gravity so it makes an object feel lighter. . O. k. . Let’s make sure we understand what is going on. . buoyant force. . This force acts upward (against gravity) on submerged objects.. That’s why you could lift a huge amount of weight underwater that you would never dream of lifting on land! You would be “helped” by this force. © 2016 Pearson Education, Inc.. Goals for Chapter 13.
