高中物理课本在讲“动量和动量守恒”一章中提到喷气式飞机和火箭都是利用反冲运动的原理制成的 .并且介绍了我国古代文明的火箭和现代火箭的知识 ,还安排了一个“自制小火箭”的小实验 ,这些内容的安排对学生理解动量守恒的原理和应用 ,加深对火箭这一尖端技术的了解 ,提高学? The high school physics textbook mentioned in the chapter “Conservation of Momentum and Momentum” that jet aircraft and rockets are made using the principle of recoil movement. They also introduced the knowledge of ancient Chinese civilization rockets and modern rockets and also arranged A small experiment of “self-made small rockets”. The arrangement of these contents will help students understand the principle and application of conservation of momentum, deepen their understanding of the rocket’s cutting-edge technology, and improve their learning.
