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.. Velocity (v) . is the rate at which an object is changing position per unit of time with a direction.. Direction is: . north, south, east, west, right, left, up, down.. Velocity changes. when one or both of the following change: . Stations 1-10. 1. What forces are involved in making a hot air balloon move?. 1. Up and Down Forces. Lift pushes the balloon up . against . the downward force of . gravity. .. Lift is due to the density inside . Pressure. 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…. 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. Convert the following to scientific notation. Distance from Sun. : 92,960,000 . miles ____. Estimated Age of universe – 14,000,000,000. Convert the following to standard form. Speed of light = 9.0 * 10. Forces & Gravity. Notes. Write down the words in yellow.. The words in white are discussion points, you may write these down, but are not required.. Gravity. Gravity is a . force. that pulls objects toward each other.. Toulouse. C. h. . Förste. 1. , S.L.

Terminal settling velocity . A gravity settler is simply a long chamber through which the contaminated gas passes slowly, allowing time for particles to settle by gravity to the bottom. The important parameter is the terminal or settling velocity of the particle, .
