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

2 VOCABULARY KEY CONCEPT CHAPTER HOME 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/m 2. Pascal (Pa) KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY pascal pressure Pressure depends on force and area. 3.3 CHAPTER RESOURCES CHAPTER RESOURCES

3 VOCABULARY KEY CONCEPT CHAPTER HOME SECTION OUTLINE SECTION OUTLINE Pressure depends on force and area. pascal pressure Pressure in a fluid acts in all directions CHAPTER RESOURCES CHAPTER RESOURCES

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

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

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

7 VOCABULARY KEY CONCEPT CHAPTER HOME 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.

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

9 VOCABULARY KEY CONCEPT CHAPTER HOME 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. Pascal’s principle Fluids can exert a force on objects. 3.4
