Delta (Physics)

In physics, "delta" (represented by the Greek letter δ or Δ) indicates a change or difference in a quantity. For example, Δx signifies the change in position, or how far an object has moved. It’s used to compare the initial and final states of a variable, helping us understand how something has evolved over time or under certain conditions. Essentially, delta measures the amount of variation, helping describe dynamics and processes in a precise way.
