Now we will discuss the important topics along with an Overview of the chapter. As an example, if you go to school or college from your home by walk, you need to know your speed and time. A great change in the modes of transport was made: Non-standard measures: The lengths of steps, arms, hands, or fingers of different people are different, therefore the distance measured with their help is not always reliable. When we measure something we quantify it. To measure the large masses we used tonne. Measurement is the process of finding the length, size, or quantity of a substance.Since ancient times, people have used several ways to measure length. Here the choice of the standard is known as Unit. Unit of Time: In SI system the unit of time is second. Answer: In our daily life we measure the following … Our learning system helps your children … Speed, density, mass, work, energy, power, etc are scalar. When a body moves in a circular path, its motion is known as circular motion. Previously it was defined as the 1/86400th part of a mean solar day.

In c.g.s and fps system, the unit of length is centimeter and foot respectively. Periodic motion: Motion in which an object repeats its motion after a fixed interval of time is called periodic motion. 1 m = 100 cm 1 AU is the distance between earth and sun. Similarly, a very small distance is measured by millimeter (mm), micrometer (μm), angstrom (Å), nanometer (nm) and femtometer (fm). To measure these quantities, units of measurements are required. For measuring large distances, metre is not a convenient unit. Physics Measurement of Basic Elements Motion Force is a physical cause that changes or may tend to change the state of rest or the state of motion of an object. Name four basic measurements in our daily life. Motion and Measurement of Distances Class 6 Chapter 10 Science Notes are the best study materials. 1 km = 1000 m.
