Time is a continuous progression of events that occur in a sequence, allowing us to measure the duration between moments. It is often divided into past, present, and future, helping us understand when things happen. Clocks and calendars are tools we use to quantify time, making it easier to organize our lives and activities. In physics, time is considered a dimension, similar to space. It plays a crucial role in various scientific theories, including Einstein's theory of relativity, which describes how time can be affected by speed and gravity. Understanding time helps us navigate our daily routines and comprehend the universe.
