FAQs on NCERT Solutions for Class 7 Science Chapter 13 - Motion And Time
1. What is motion and time, according to Chapter 13 of Class 7 Science?
When there is a change in the position of an object with respect to time, it is known as motion. In Class 7 Motion and Time, you will learn about different motions, including why some motions are fast, and others are slow, speed and how it is measured, how time is measured, and the different units of speed and time. You will also learn how to draw and understand a distance-time graph. You will solve some practical life problems too.
2. What is the unit of Time, according to Chapter 13 of Class 7 Science?
Generally, the basic unit of time, that is second, is used. The bigger units of time are minute and hour. The symbol of the second is s. Though it is the most commonly used unit of time, other units are also used depending on the need. For example, no one tells their age in terms of seconds, minutes or hours, they use year instead of that.
3. What is Speed, according to Chapter 13 of Class 7 Science?
Speed can be referred to as the distance covered by any moving object in unit time. Its basic unit is meter per second (m/s), but the speed of fast-moving vehicles is often expressed in kilometres per hour (km/hr) also. Fast-moving objects have high speed, i.e. they cover more distance in unit time than those of low speed which covers less distance in unit time.
4. What is the unit of speed, according to Chapter 13 of Class 7 Science?
The unit of speed is distance /time, which is meter per second (m/s). Time is, of course, expressed in minutes and hours, and distance can also be expressed in other units like km, cm, mm, etc. Therefore, speed has many other units, like cm/min., km/hr, etc. These units are used only when required.
