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.
