PRESSURE
Compare these two scenarios:
A: You use 10N of force to push a nail into a balloon.
B: You use 10N of force to push the palm of your hand into a balloon.
How are these two scenarios different? How are they the same? WHY??
Pressure is the amount of force applied to a specific area.
P = Force / Area
This is otherwise calculated as P = Newtons / cm2(squared) or in more practical terms P = pounds/square inch (PSI)

Pascal's Law Squeezing a water-filled balloon demonstrates Pascal's Law. When you squeeze the balloon on one end the water will transfer that pressure to the balloon on the other end in equal amounts and in all directions. Pascal's law basically states that PRESSURE exerted on a contained fluid is transmitted undiminished in all directions throughout the fluid. A Cartesian Diver is a simple but cool experiment that we will make in class. Click here to get instructions. | |
