Now, we will learn about Velocity Time Graphs . Velocity-Time Graphs: To draw velocity time graphs, we will use the three equations of motion. Case 1: Velocity-time graphs with constant velocity (zero acceleration) When the velocity is constant, the velocity time graph, with Y-axis denoting velocity and X-axis denoting time, will be like: As clear from the graph, the velocity is constant (c) throughout the time interval.
Nikola Tesla first invented the radar because he knew the America needed help in World War I since German U boats sank hundreds of our boats. Sure it could only detect roughly 6feet out, but it was a start.
Fire-control radar helps aim a gun or missile so that it will hit the target when fired and must be more accurate than search radar. The U.S. military has also developed specialized types of radar. For example, Miniature Synthetic Aperture Radar (MSAR) is used on aircraft to provide high-quality images in all kinds of weather. History of Radar Radar technology began with experiments using radio waves in the laboratory of German physicist Heinrich Hertz in 1887.
