RBSE Class 6 Science Chapter 10 Notes Motion and Measurement of Distances

→ Invention of the wheel made a great change in modes of transport.

→ The invention of steam led to the development of new means of transport.

→ In ancient times„people used length of a foot, the width of a finger, the distance of a step as units of measurement. This caused confusion and a need to develop a uniform system of measurement arose.

→ The system of units naw used is known as the International System of units (S.I. units).

→ The SI unit of length is metre.

→ Each metre (m) is divided into 100 equal divisions, called centimetre (cm). Each centimetre has 10 equal divisions, called millimetre (mm). Thus,

• 1 m = 100 cm
• 1 cm = 10 mm

→ For measuring large distances, we use the unit kilometre (km).
1 km = 1000 m

→ Change in the position of an object with time is called motion.

→ Types of motion :
