PS2B - 交互类型


Paul Andersen explains how objects interact when touching and at a distance. Electromagnetic forces are very important when objects are touching and fields explain both electromagnetic and gravitational forces. The strong and weak nuclear forces can result in radioactive decay. A brief description of Newton's Law of Universal Gravitation and Coulomb's Law are includes.

下一代科学标准物理科学纪律核心思想2B:互动类型

保罗安德森解释了对象在触摸时和距离时如何交互。当物体触摸时,电磁力非常重要,磁场解释电磁和重力。强大而弱势核动力可能导致放射性衰变。纽顿普遍引力和库仑定律的简要描述包括。
