Physics review of third grade The ninth chapter, pressure one, learning target 1, know what is called pressure, through the experiment to understand the concept of pressure, can use pressure formula for simple calculation, know the method of increasing and reducing pressure. 2, through the experiment to explore the liquid pressure with what factors, know that the liquid pressure formula will use formula for correlation calculation, know the principle of connected device. 3. Know the characteristics of closed liquid pressure and its application (hydraulic technology). 4, know the existence of atmospheric pressure, know the size of a standard atmospheric pressure, understand the method of measuring atmospheric pressure, understand the instrument for measuring atmospheric pressure, and know the relevant examples of using atmospheric pressure. 5, through the experiment to explore the relationship between fluid pressure and velocity, we will use the relationship between fluid pressure and flow velocity to explain the phenomenon. Points of knowledge review two, knowledge points (a), 1 pressure definition: on the surface of objects called force pressure. 2. directions: on the surface by pressure of the object, not necessarily the vertical downward pressure and gravity. 3.: when the object is placed in the horizontal plane, the size of the object of gravity pressure object 4.. The effect of pressure with pressure and related research, using the method. (two) the pressure 1. definition: object is called pressure pressure. 2. physical meaning: the pressure is used to represent physical quantities. 3. formula: p=, unit: 4. change pressure method: (1) method to reduce the pressure the pressure increased; when the force area is reduced. (2) increasing pressure: the
