## Important points of NCERT Exemplar Class 6 Science Chapter 10: Motion and Measurement of Distance

Story of Transport

1. The early humans would travel mostly on foot and carry their things on their backs, later they began to domesticate animals and use them for transportation.
2. The earlier transportation over water bodies was mostly done by boats which were merely hollow logs of wood, later with the knowledge of building tools of wood, streamlined boats were developed.
3. After the invention of the wheel, there were instances where the design of the wheel was constantly ignored only to reach this age of supercars.
4. With the invention of the wheel, carts were made to be pulled by the animals domesticated.
5. Later, along with the invention of the steam engine, various railroads began to be constructed. The steam engine pulled carriages and wagons, totally changed the game of transport.
6. Later in the 19th century, automobiles were developed; motorboats and ships were used as means of transport on water.
7. In the most recent history, in the 20th century, electric trains, monorails, supersonic aeroplanes, and spacecraft are some of the contributions of humans in the field of transport.

Measurement

The comparison of an unknown quantity with some known quantity to know the size of an object or the distance between two points is known as measurement.

The known quantity which is fixed is called a Unit.

A measurement consists of mainly two parts, a number and the unit of measurement.

There used to be various units of measurement of length such as the width of a finger, the length of the foot. In ancient times, cubit and yard were also earlier units of measurement.

Standard Units of Measurement

In 1790, the French invented a standard system of measurements, known as the metric system. It was later accepted globally and is now known as the International System of Units (SI Unit). The SI unit for length is Meter which can be converted into other units such as Centimeter, Millimeter, or Kilometer.

A pace or a footstep cannot be used as a standard unit of length because it varies from person to person in size and may lead to confusion in measurements.

## NCERT Exemplar Solutions for Class 6 Science Chapter 10- Important Points to Remember

1. Place the scale along with the length of the object. Make sure it is in contact with the object.
2. Begin the observation from a clearly visible mark on the scale.
3. Keep your eyes right in front of the point at which the length is to be measured.
• Motion

When there is a change in the position of an object with respect to time. It is said to have undergone motion.

Types of motion:

1. Rectilinear motion
2. Circular motion
3. Periodic motion

Examples:

1. Rectilinear motion: gravitational force on falling objects, kids sliding down from a slide
2. Circular motion: an artificial satellite orbiting Earth at a fixed height, a stone which is tied to a rope and swung in circles
3. Periodic motion: Pendulum and Needle of a sewing machine
