This course covers the fundamentals of Newtonian mechanics, including kinematics, motion relative to accelerated reference frames, work and energy, impulse and momentum, 2D and 3D rigid body dynamics. The course pays special attention to applications in aerospace engineering including introductory topics in orbital mechanics, flight dynamics, inertial navigation and attitude dynamics. By the end of the semester, students should be able to construct idealized (particle and rigid body) dynamical models and predict model response to applied forces using Newtonian mechanics.

This web page features a collection of Easy Java Simulations developed by secondary teachers for use in introductory high school physics courses. Topics include astronomy, momentum and collision, projectile motion, Gauss's Law and electric field, special relativity, and more. Each simulation is accompanied by a standards-based lesson plan and printable student guides. Users may run the simulations as a Java applet or may directly download a jar file version. The materials in this collection were created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations. To modify or customize the model, See Related Materials for detailed instructions on installing and running the EJS Modeling and Authoring Tool. This resource is part of Project ITOP (Improving the Teaching of Physics), a graduate program offered at University of Massachusetts-Boston. The archived computer models are hosted and maintained as part of the BU Physics Simulation collection.

This course provides students with a scientific foundation of anthropogenic climate change and an introduction to climate models. It focuses on fundamental physical processes that shape climate (e.g. solar variability, orbital mechanics, greenhouse gases, atmospheric and oceanic circulation, and volcanic and soil aerosols) and on evidence for past and present climate change. During the course they discuss material consequences of climate change, including sea level change, variations in precipitation, vegetation, storminess, and the incidence of disease. This course also examines the science behind mitigation and adaptation proposals.

This part of the course Introduction to Aerospace Engineering is focused on two aerospace disciplines: "space and orbital mechanics" and "structures and materials". These topics are discussed in detail and will provide an understanding for both aircraft and for spacecraft/space missions. Study Goals- List/describe the reasons for going into space and the principles of rockets, including their trajectories.- Motivate the selection of spacecraft configurations depending on the mission and identify the main elements of a satellite.- Describe the features of the space environment and their consequences for space activities.- Determine elementary satellite orbits, transfer orbits and maneuvers- Describe and work with elementary space propulsion aspects: launch, velocity budget and rocket equation- List the characteristics of typical aerospace materials & structures and describe their meaning and relevance- List the main structural elements of an aerospace vehicle and describe their functions and performance

Learn Motion of Earth, Sun, Moon & Satellites in Orbit : Astronomical Time Standards and Time Conversions, Positional Astronomy - earth orbit around sun, Position of Sun on Celestial Sphere, Position of Earth on Celestial Sphere, Satellites Orbit Elements - ephemeris, keplerian elements, state vectors, Satellites Motion around Earth - orbital & positional parameters, Satellite Pass for Earth Station - prediction of ground trace are addressed.

Satellite Engineering introduces students to subsystem design in engineering spacecraft. The course presents characteristic subsystems, such as power, structure, communication and control, and analyzes the engineering trades necessary to integrate subsystems successfully into a satellite. Discussions of spacecraft operating environment and orbital mechanics help students to understand the functional requirements and key design parameters for satellite systems.

key words: energy conservation, law of atmospheres, satellite drag

The goals of this exercise are to put the laws of large-scale orbital dynamics into a space physics context while introducing numerical and semi-empirical modeling methods. The spreadsheet simulation consists of two linked spreadsheets and their associated plots. One spreadsheet contains density and temperature for the lower 1000 kilometers of the Earth's atmosphere, and the other contains the orbit simulation. A concept map guides students in developing formulations for describing satellite motion in an atmosphere whose density varies exponentially. At the conclusion of the laboratory students produce temporal profiles of altitude, velocity, energy, and drag force on a low-Earthorbiting satellite. A post-laboratory questionnaire focuses student thought on the physics and modeling process.
