    1. Buoyancy Notes By Mr. Dummett….and Bill Nye

    2. Bill Nye Buoyancy Video questions Buoy is latin for ______ Buoyancy is the “_____ force” Things float because ___ is heavy. Things float because they have ___ density. Displace = _____________

    3. Buoyancy Buoy is latin for Float Buoyancy is the “floating force” Things float because H2O is heavy. Things float because they have low density. Displace = push water away

    4. Buoyancy Archemedes Principal: A floating object displaces water, the water displaced weighs the same as the object’s weight.

    5. Buoyancy Forces working on floating objects: Gravity pulls it down

    6. Buoyancy Forces working on floating objects: Gravity pulls it down The displaced water pushes back on the object-this is the BUOYANT FORCE

    7. Buoyancy Gravity pulls it down Buoyant force pushes up. Floating: Gravity = Buoyant force

    8. Buoyancy Gravity pulls it down Buoyant force pushes up. Sinking: Gravity > Buoyant force

    9. Buoyancy Gravity pulls it down Buoyant force pushes up. Rising object: Gravity < Buoyant force

    10. Why do things float? Things float if their volume is larger than their mass. Things sink if their mass is larger than their volume.

    17. Why do things float A thing will float if its mass is smaller than its volume. A thing will sink if its mass is bigger than its volume

    18. Today’s Lab Buoyancy Lab 1 Newton (N) = 100 grams 15 grams 15 grams / 100 = 0.15 N 35 grams 35 grams / 100 = 0.35 N

    23. Why do things float? Tonnage (gross): 46.328 tons Displacement at time of collision: 48,478 tons (figures vary) Mass = 42,116,363 Kg Volume (displacement) = 44,070,909 L Density = M/V = 42,116,363 Kg / 44,070,909 L = 0.96 Kg/L
