Length is a fundamental physical quantity that helps us determine how long or short an object is. Measurement of length is crucial in everyday life, engineering, architecture, and science.
Understanding conversions between units is essential:
Example: Convert 5 km to meters:
5 km = 5 × 1000 = 5000 meters.
Using rulers, measuring tapes, etc.
Used for large distances like roads or rivers.
Problem: A rope is 6 meters long. If it is cut into 3 equal parts, what is the length of each part?
Solution: 6 m ÷ 3 = 2 m each.
Length measurement is an essential concept that involves units, conversions, and different tools for accuracy.
