👉 Isochrony in physics refers to the condition where two or more objects move at the same speed or velocity, with no difference between their durations of motion. This is a fundamental concept in classical mechanics and describes how objects can be described as being "isochronic" if they have the same average acceleration over time. For example, consider a car moving along a straight road. In this case, the car's instantaneous speed at any given moment (time) would be equal to its average speed
