CK12 21st Century Physics: A Compilation of Contemporary and Emerging Technologies - CK-12 Foundations’s 21st Century Physics Flexbook: A Compilation of Contemporary and Emerging Technologies covers the following chapters: Toward Understanding Gravitation – gravitation, astronomy and cosmology. Nuclear Energy - non-mathematical introduction to atomic nucleus and nuclear fission. The Standard Model of Particle Physics - Building blocks of matter and forces that hold these particles together The Standard Model and Beyond- Current experiments in particle physics, large particle colliders, equipment and instrumentation and emerging theories. A Brief Synopsis of Modern Physics - origin, components, implications, and lingering problems. Introduction to Nanoscience - discovery and study of phenomena at molecular scale (between 10 and 100nm Biophysics (Medical Imaging) - medical imaging technologies and their foundations in physics Kinematics: Motion, Work, and Energy – terms about motion, how work is done and types of energy Laboratory Activities - 15 physics experiments using 21st century technology Statistical Physics and Random Walks – Modeling and Simulation in the Physics Classroom - using modeling and simulation to teach physics Modeling and Simulating NASA's Launch Abort System - Physical laws and assumptions applied with a computer program to simulate the motion of NASA’s Launch Abort System to better understand function and improve design. Laboratory Activities - This chapter presents 15 physics experiments that utilize 21st century technology to conduct investigations. The PASCO Xplorer GLX handheld interface is highlighted with downloadable labs hyperlinked throughout the chapter. Statistical Physics and Random Walks – Modeling and Simulation in the Physics Classroom - This chapter presents examples of how physics content can be taught using modeling and simulation. Modeling and Simulating NASA's Launch Abort System - It is valuable to model and simulate complex systems to better understand how they work and improve their design. Physical laws and assumptions are applied using a computer program to simulate the motion of NASA’s Launch Abort System.
