NCERT Solutions for Class 7 Science Chapter 13 Motion and Time In Hindi PDF Download
FAQs on NCERT Solutions for Class 7 Science Chapter 13 - In Hindi
1. What is the basic unit of speed?
The basic unit or SI unit of measuring speed is meters per second. It is denoted by m/s. The significance of the SI unit of speed is that it helps determine the meters an object can travel usually within a second. For example, if an object can travel 10 meters within a second, then the speed of the object will be written as 10 meters per second or 10 m/s.
2. What kind of motion is involved in a horse pulling a cart on a straight road according to Chapter 13 of Class 7 Science?
According to the NCERT Solutions for Chapter 13 of Class 7 Science there are three types of motions. These are known as straight-line, oscillatory, and circular motion. The motion that takes place when a cart is being pulled by a horse on a straight road is classified as straight-line motion. The reason for this classification is that since it is a straight road, any motion on it would form a straight line.
3. How to solve the numericals from Chapter 13 of Class 7 Science effortlessly?
To be able to solve numerical effortlessly, students must first ensure that they have thoroughly read and understood the theories and concepts behind each numerical. Once you know the theory and understand the working of the related formulas, memorize the formulas. Practice using these formulas for solving numerical questions and refer to NCERT Solutions in case you face difficulty. These steps will help you solve numericals for all physics chapters including Chapter 13 of Class 7 Science.
4. What are the topics discussed in Chapter 13 of Class 7 Science?
