5 True/False Questions
As elevation increases, pressure → decreases
What does Bernoulli's principle state? → The faster the fluid moves, the less pressure it exerts within the fluid.
How can a ship float? → the amount of water the ship displaces increases the buoyant force and therefore has a net force greater upwards than down.
What is area measure by? → Newtons
What is pressure measured by? → Newtons
