This document contains a practice worksheet with multiple choice and short answer questions about motion graphs. The questions ask students to identify terms like motion, reference point, velocity and speed from definitions. They are also asked to analyze motion graphs to determine if objects are moving at constant speed, accelerating, decelerating or stopped based on the shape of the graph. They must also calculate values like speed, average speed and velocity from the graphs.

This document provides a summary of the history of exobiology and astrobiology at NASA. It discusses how the fields have evolved over the past 50 years from early speculation about life on other planets to the establishment of NASA's Exobiology program in 1960 and the expanded Astrobiology Program in the 1990s. The summary also highlights some of the key figures and experiments that helped shape our understanding of the potential for life elsewhere, such as the Miller-Urey experiment which demonstrated how organic molecules could form in conditions similar to the early Earth.
