Buoyancy Video Notes
1.) What does it mean to "displace" water?
To displace water is to replace an amount of water with the objects weight.
2.) Why does the clay ball sink but the same size clay boat float? The reason that the clay ball sinks is because it's shaped to make it sink.
3.) Things displace as much water as they.. weight
4.) Who was Archimedes? What did he discover? Archimedes was a Greek mathematician, physicist, engineer, inventor, and astronomer . he discovered the principle of buoyancy as well as how to determine the exact value of pi and how to find the volume of a sphere.
5.- How do fish control their buoyancy ?
Fish control their buoyancy by their "swim bladder", they do this by inhaling. They go to the surface then when they decrease the air on their gills they sink.
6.- Define the following:
Negatively Buoyant : When the objects sinks.
Positively Buoyant: When an objects floats.
Neutrally Buoyant: When the object stays at the middle , does not sink.
7.- How hot air balloons work?
The hot air balloons work because they have buoyancy. The hot air makes them go up by displacing the cool air which makes it go more faster.
