- c when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.
- d Pascals
- e the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.

5 True/False questions
How could you measure pressure? → the earth's atmosphere is constantly applying pressure (example)
What is buoyancy? → a material that can easily flow
What is pressure? → the earth's atmosphere is constantly applying pressure (example)
How do atomizers take advantage of Bernoulli's principle? → the flask at the top (when you squeeze it) creates a greater fluid speed which causes a lower pressure and the pressure in the bottle is greater and causes the liquid in the bottle to move up and out of the bottle.
How does a submarine dive? → By increasing its density with water and overcoming the buoyant force by adding more weight and not changing the volume and therefore not displacing anymore water to increase the buoyant force.
