物理学习要特别注意物理知识之间的连贯性,做到融汇贯通.例如:p=ρgh公式本来是液体内部压强计算式,但它也可用来解决浮力问题,还可以解释大气压强等方面的知识,并且在使用中可使问题简单化,使学习者更容易理解和掌握,下面举例说明:一、用p=ρgh公式解决浮力问题[例1]有一块冰 Physics learning should pay special attention to the continuity between physical knowledge and achieve convergence. For example, the formula p=ρgh is originally a liquid internal pressure calculation formula, but it can also be used to solve buoyancy problems, and it can also explain aspects such as atmospheric pressure. Knowledge, and the use of the problem can be simplified, so that learners easier to understand and grasp, the following examples: First, solve the buoyancy problem with the p = ρgh formula [Example 1] there is a piece of ice
