  1. Take out your packets. Prepare for the review game. DO NOW

  2. If you divide the force exerted on a surface by the total area of the surface, you will know • A.density • B.pressure • C.Lift • D.Buoyantforce

  3. If you know the weight of an object that floats, you know the • A.Object’sdensity • B.Object’s mass • C.Object’svolume • d. Buoyant force

  4. If you divide the mass of an object by its volume, you know the object’s • A.mass • B.weight • C.Density • D.pressure

  5. The concept that an increase in pressure on a confined fluid is transmitted equally to all parts of the fluid is known as • A.Pascal’sPrinciple • B. Bernoulli’s principle • C.Archimedesprinciple • D.Newton’sthird law

  6. Which of the following is NOT the SI unit of pressure? • A.N/m2 • B. newton • C. Pa • D. pascal

  7. The concept that the pressure in a fluid decreases as the speed of the fluid increases is known as • A.Pascal’sprinciple • B.Bernoulli’sprinciple • C.Archimedes’ principle • D.Newton’sfirst law

  8. Pressure is • A. Force x area • B. Force + area • C. area ÷ force • D. force ÷ area

  9. At higher elevations, air pressure is • a. Less because there is less air above • B.Greater because there is more air below • C.Lessbecause gravity is stronger • D.Lessbecause the air is moving

  10. When pressure is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. This fact is called • A. Pascal’s principle • B. Archimedes’ principle • C. Newton’s Principle • D. Bernoulli’s Principle

  11. An object under water feels lighter than it does in air because • A.Airpressure • B.Fluid speed • C.Buoyancy • D.temperature

  12. If you blow a stream of air between two balloons that are next to each other, the balloons • A. rise   • B. move away from each other • C. Move toward each other • D. Move randomly

  13. An object is dropped into a beaker containing liquid. The object drops to the bottom of the beaker. Therefore, the • A. Density of the object is greater than the density of the liquid. • B.Densityof the object is less than the density of the liquid. • C.Massof the object is less than the mass of the liquid • D.Volumeof the liquid displaced is more than the volume of the object.

  14. The rising of smoke up a chimney is partially explained by which principle • A.Bernoulli’sprinciple • B.Newton’sthird law • C.Pascal’sprinciple • D.Archimedes’ principle

  15. Air above an airplane wing is moving faster than air below an airplane wing. This causes the plane to • A.accelerate • B.Slow down • C.Increaseits elevation • D.Decreaseits elevation

  16. Bubbles rise in water because they are • a. so tiny • B.Less dense than water • c. More dense than water • D.Fluids

  17. The density of a substance is its __________________ per unit __________________ • A.Mass, density • B.Volume, mass • C.Mass, volume • D.Density, volume

  18. A device that increases force that works because of Pascal’s Principle, such as the braking system of a car, is called a ___________________ device • A.Lift • B.Hydratitic • C.Hydraulic • D.Stopping

  19. Water pressure _________________________, as depth _________________________ • A.Increases, decreases • B.Increases, stays the same • C.Decreases, increases • D.Increases, increases

  20. A _____________ is a material that can easily flow. • A.Solid • B.Fluid • C.boat • D.Gas

  21. The pressure exerted by the gas in Earth’s atmosphere is called • A.Buoyantforces • B.Forces • C.Gravity • D.Atmosphericpressure

  22. _____________________ is equal to the force exerted on a surface divided by the total area over which he force is exerted.

  23. You can measure atmospheric pressure with an instrument called _______________________.

  24. A ___________________ is a material that can easily flow.

  25. ______________________________________ _____________________________ states that when force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.

  26. The wing of an airplane is designed to produce __________________, or an upward force.

  27. Water and other fluids exert an upward force called the ____________________________ ___________________ that acts on a submerged object.

  28. The ____________________ of a substance is its mass per unit volume.

  29. ______________________________ _____________________________ states that the faster a fluid moves, the less pressure the fluid exerts.

  30. A _________________________________ ________________________ uses liquids to transmit pressure in a confined fluid.

  31. The unit of pressure is called the _____________________.

  32. ____________________________ _________________________________ states that the buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces.

  33. Name two hydraulic systems that auto mechanics would be familiar with

  34. A sphere made of steel is put in water and surprisingly it floats. Develop a possible explanation for this observation.

  35. Why do you seem to weigh more in the air than you do in the water?
