Abstract

This article explores the trajectory of rockets and artificial satellites in the atmosphere, specifically focusing on the effects of drag forces. It discusses different types of orbits and highlights the lack of information on drag forces in high school textbooks. The article proposes a new calculation method to help students understand spiral motion caused by drag forces and also delves into the use of energy and power in analyzing these effects. The document further discusses the drag force experienced by objects in Earth's atmosphere, providing equations for different scenarios based on the Reynolds number. It also covers the motion of objects in circular paths and concludes with an equation describing the trajectory of objects experiencing drag force. The text emphasizes the study's focus on spherical objects passing through the stratosphere and troposphere, providing physical constants and presenting results of different mass values on the trajectory. The authors derived formulas for spiral trajectories based on energy loss caused by drag forces, and computational estimations showed that ideal spherical objects subjected to drag forces perform spiral motion. The study's findings can aid students and teachers in understanding the trajectory of objects experiencing drag forces. [Extracted from the article]
