3.3 pressure Pressure depends on force and area. Force Pressure = Area
pascal A measure of how much force is acting on a certain area; how concentrated a force is. Pressure depends on surface area. Pressure = Force Area CHAPTER RESOURCES KEY CONCEPT SUMMARY

3.3 Pascal (Pa) Pressure depends on force and area.
The unit used to measure pressure; one pascal is the pressure exerted by one newton of force on an area of one square meter, or one N/m2. CHAPTER RESOURCES KEY CONCEPT SUMMARY

Pressure depends on force and area.
3.3 Pressure depends on force and area. Pressure in a fluid acts in all directions. pressure pascal CHAPTER RESOURCES SECTION OUTLINE

Pressure depends on force and area.
3.3 Pressure depends on force and area. Pressure = Force Area pressure Pressure in a fluid acts in all directions. pascal VISUALIZATION See how to lift a stool using a rubber mat and air pressure. SIMULATION Explore how a fluid produces pressure. CHAPTER RESOURCES SECTION OUTLINE

Fluids can exert a force on objects.
3.4 Fluids can exert a force on objects. • Buoyant force is equal to the weight of the displaced fluid. buoyant force Bernoulli's principle Pascal’s principle CHAPTER RESOURCES SECTION OUTLINE

3.4 buoyant force Fluids can exert a force on objects.
Bernoulli's principle The upward force on objects in a fluid; often called buoyancy. Pascal’s principle CHAPTER RESOURCES KEY CONCEPT SUMMARY

Try to crush the egg applying equal pressure.
Air pressure Mark intervals of 1cm along the length of one straw Fill cup half way with colored water Hold the marked straw in the water (do not touch the bottom of the cup Blow across the top of the straw with different speeds and observe. Try to crush the egg applying equal pressure.

3.4 Bernoulli's principle Fluids can exert a force on objects.
buoyant force Bernoulli's principle Bernoulli's principle An increase in the speed of a fluid decreases the pressure within the fluid. Pascal’s principle CHAPTER RESOURCES KEY CONCEPT SUMMARY

3.4 Pascal’s principle Fluids can exert a force on objects.
A statement that says when an outside pressure is applied at any point to a fluid in a container, that pressure is transmitted throughout the fluid with equal strength.
