Below are the four links that relate to Unit 6 of our class (Gravity, Mass, Density and Weight, Buoyancy, Bernoulli’s Principle, Scaling):
- Buoyancy: What Makes Something Float or Sink?
- This video provides a quick and simply illustration to understand the basic concepts of buoyancy (floating and sinking). It also explains density and Archimedes’ Principle in relation with buoyancy. This is a very basic video, but one that helped me gain a greater understanding of buoyancy.
- Bernoulli’s Principle: Demonstrated
- Bernoulli’s Principle states that as the velocity of fluid increases, the pressure of that fluid decreases. This explains that pressure and velocity in a moving fluid are inversely proportional. This video will provide the viewer a demonstration, explanation, and some examples of how Bernoulli’s Principle works. Enjoy!
- What is a Plimsoll Line?
- This is a short article that defines what a Plimsoll line is. According to the article, a Plimsoll line is a reference mark located on a ship’s hull that indicates the maximum depth to which the vessel may be safely immersed when loaded with cargo. Put simply, a commercial ship is properly loaded when the ship’s waterline equal the ship’s Plimsoll line. Interesting!
- Are Mass and Weight the Same Thing?
- This is a fun video (the commentator has a sweet accent) that explains the difference between mass and weight. Whereas mass is the amount of matter present in an object, weight is the measure of the gravitation pull on an object. Take a look!
Thanks for checking out my Unit 6 links!
