In the formula S=D÷T, what does the "S" stand for?

In the formula S = D ÷ T, "S" stands for Speed. This equation expresses the relationship between distance (D), time (T), and speed (S), which is calculated by dividing the distance traveled by the time taken.

Speed is a fundamental concept in both RADAR and LIDAR technologies, as these systems often measure the speed of an object to determine its position and motion. For instance, in the context of RADAR, the time taken for a signal to travel to an object and back (the round-trip time) is crucial for calculating how far away that object is and how fast it is moving. The concept of speed is vital for interpreting data in applications such as traffic monitoring, aviation, and meteorology, where understanding the velocity of objects is essential for accurate assessments and predictions.
