👉 In constant, I mean that there is no change or variation in a variable. In other words, if you have a variable A and its value changes over time, it will remain constant as long as the value of the variable does not change. For example, let's say you are measuring the temperature of an object every 10 minutes for 3 hours. The temperature would remain constant throughout this period because no matter how fast or slow the object moves, its temperature remains constant.
