Alpha Centauri is the naked-eye star nearest to our sun. It is 4-1/2 light-years away. This is your destination. Before lift-off, you synchronize your rocket's clock with the clock at mission control. When you return from your journey, will the clocks still have the same reading? This is just one of the "relativity riddles" your students will encounter - and solve - in RelLab's interactive relativity laboratory. In this open-ended environment, they can investigate both low-speed motion explained by Newton's mechanics and high-speed motion described by Einstein's theory of special relativity. Start with everyday phenomena and move on to explore the rich paradoxes of special relativity. In no time, your students will develop a keen intuition about the world of the very fast. With RelLab, you can create simulations of physical systems in two space dimensions and view them in real time. You have the tools to design any scenario imaginable, as long as it does not violate the presently known laws of nature. Your students will begin to see the implications of Lorentz transforms and understand why a reference frame is critical. They will learn how length contracts, how time dilates, and how simultaneity depends on the velocity of the observer. The RelLab manual contains a comprehensive tutorial to familiarize you with the program's operational features, its tool palette, and frame clock. The instructor's guide offers teaching suggestions, based on extensive classroom studies, for using RelLab in both high school and college-level courses. The final section contains nine fascinating relativity paradoxes guaranteed to motivate your class and encourage exploration! 88 pp. System Requirements:
