The NCERT Class 7 Social Science Chapter “Measurement of Time and Motion” helps students understand how time and motion are measured using scientific methods and instruments. It explains key concepts like speed, distance, and uniform and non-uniform motion, along with tools such as clocks, sundials, and stopwatches.
Through practical examples, students explore how motion is part of daily life — from moving vehicles to rotating planets. The chapter also discusses how accurate time measurement has influenced transportation, technology, and global communication. It builds a strong foundation in scientific observation and reasoning.
