What effect does a buoyant force have on a submerged object?
a) It causes the object to sink
b) It causes a net force acting upward on the object
c) It causes the object to float in a fluid
d) It causes a net force acting downward on the object

Pressure can be measured in units of
a) newtons
b) newtons per square centimeter
c) newtons per centimeter
d) newtons per cubic centimeter

How is the pressure applied by a fluid related to how fast the fluid moves? (think airplane wing)
a) the faster the fluid, the higher the pressure
b) the faster the fluid, the lower the pressure
c) its Magic
d) the slower the fluid, the lower the pressure

If the density of the object is equal to the density of the fluid in which it is submerged,
a) the object sinks
b) the object floats
c) the object will sink, then rise, then keep repeating this cycle
d) the object will neither float nor sink, but will suspend at a constant level

Fluid pressure is the total force exerted by the fluid divided by
a) the area over which the force is exerted
b) the acceleration of the force
c) the gravitational pull within the fluid
d) water pressure or depth

What scientific rule states that the pressure exerted by a moving stream of fluid is less than the pressure of the surrounding fluid?
a) Archimedes' principal
b) Pascal's principal
c) Bernoulli's principal
d) Newton's third law of motion

Which of these multiplies a force by transmitting it to a large surface area?
a) a hydraulic system
b) a buoyant force
c) a balanced pressure
d) a force pump

When a force is applied to the 2 liter bottle, the pressure exerted on the water increased. Why did the eyedropper sink?
a) it's magic
b) the increased water pressure caused the density of the eyedropper to increase
c) the increased water pressure caused the density of the eyedropper to decrease
d) the increased water pressure caused the density of the eyedropper to not change at all

Much of the lift that enables an airplane to fly can be explained using
a) Pacal's principal
b) Newton's 1st law of motion
c) Archimedes' principal
d) Bernoulli's principal

When the force was removed from the 2 liter bottle, the pressure exerted on the water decreased. Why did the eyedropper float?
a) The increased water pressure caused the density of the eyedropper to decrease
b) It's magic
c) The decreased water pressure caused the density of the eyedropper to decrease
d) The decreased water pressure caused the density of the eyedropper to not change at all
