Hewitt Drew-It! PHYSICS Screencasts

58. Liquid Pressure
Liquid pressure depends on the density and the height, not the volume.

59. Buoyancy
Why is buoyancy an upward force? Why not sideways, or in some other direction?

60. Archimedes
Archimedes' principle has a fascinating application, the famous Falkirk Wheel in Scotland.

61. Buoyancy on a Submarine
How is the buoyancy of a submarine affected when it is submerged?

62. More on Buoyancy
How density affects sinking, floating, and remaining in equilibrium doing neither.

63. Buoyancy Problems
Problem solving with buoyancy is investigated.

64. Pascal's Principle
Piston arrangements and examples of multiplying forces.
