Look at the pressure triangle. How do we calculate the area?

• f ÷ a

• f x p

• p x f

• f ÷ p

Pressure depends on depth

• true

• false

A force is applied in a closed container, the pressure increases the same amount. EX: squeezing a water bottle or toothpaste

• Archimede's Principle

• Pascal's Principle

• Bernoulli's Principle 

The amount of force pushing on an area is the definition of....

• Fluid

• Viscosity

• Barometer

• Pressure

Pressure can be measured in Pascals (Pa) or Newtons per square meter.

1 Pa = 1N/m²

• True

• False

Fluids can be...

• solids

• liquids

• gases

• liquids or gases

In rectilinear translation, if an open rectangular container with the length (L) two times the height (H) moving horizontally is filled with 2/3H of water, will there be water spilled if the acceleration (a) is equal to acceleration due to gravity (g)?

• NO

• YES
