Class 6 Science Chapter 5 PDF: Measurement of Length and Motion (Curiosity)

Class 6 Science Chapter 5, Measurement of Length and Motion, starts with Deepa getting a new school uniform measured in metres and char angula. It covers traditional vs SI units of length, correct scale usage, measuring curved lines, reference points, and linear, circular and oscillatory motion.

What Class 6 Science Chapter 5 Covers

5.1–5.4 Measuring Length & Standard Units compares body-part units (handspan, angula, cubit, pace) with the SI unit of length—the metre (1 m = 100 cm, 1 cm = 10 mm, 1 km = 1000 m)—and shows correct scale placement, eye position to avoid parallax error, using a broken-zero scale (5.3), and measuring curved lines with a thread (5.4).

5.5–5.7 Reference Point, Moving Things & Types of Motion defines position relative to a fixed reference point (5.5), distinguishes rest and motion (5.6), and classifies motion into linear motion, circular motion, and oscillatory motion (5.7).

FAQ

How do you measure length using a scale with a broken zero mark?
Start from any clear full mark (such as 1.0 cm) and subtract that starting reading from the final reading at the other end of the object.

What are the three main types of motion covered in Chapter 5?
Linear motion (moving along a straight line), circular motion (moving along a circular path), and oscillatory motion (moving to and fro about a fixed position, both circular and oscillatory being periodic).
