Duration: Duration in physics is the interval of time between two events. It is a fundamental quantity in physics, and it is used to measure the time it takes for processes to occur. Duration is measured in seconds in the International System of Units (SI). Duration allows us to understand and predict the behavior of the physical world. For example, we can use duration to calculate the speed of an object or the energy of a photon._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
