Thought-Process to Discover Knowledge

Welcome to nubtrek.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

Read in the blogs more about the unique learning experience at nubtrek.

User Guide

To make best use of nubtrek, understand what is available.

nubtrek is designed to explain mathematics and science for young readers. Every topic consists of four sections.

nub,

trek,

jogger,

exercise.

User Guide

nub is the simple explanation of the concept.

This captures the small-core of concept in simple-plain English. The objective is to make the learner to think about.

User Guide

trek is the step by step exploration of the concept.

Trekking is bit hard, requiring one to sweat and exert. The benefits of taking the steps are awesome. In the trek, concepts are explained with exploratory questions and your thinking process is honed step by step.

User Guide

jogger provides the complete mathematical definition of the concepts.

This captures the essence of learning and helps one to review at a later point. The reference is available in pdf document too. This is designed to be viewed in a smart-phone screen.

User Guide

exercise provides practice problems to become fluent in the concepts.

This part does not have much content as of now. Over time, when resources are available, this section will have curated and exam-prep focused questions to test your knowledge.

In a bucket there is 20 liter water and another 10 liter water is poured in. How much water is there in the bucket?

• 20+10
• 30
• both the above
• none of the above

Two taps simultaneously fill a bucket. one fills at 20 liter per hour and another fills at 10 liter per hour. How much water will the bucket have at the end of an hour?

• 30
• 20
• 10
• none of the above

Answer is '30'. Scalar quantities can be added continuously.

Summary:
We have seen that two ways scalar quantities can be added - Sequentially and Continuously.

A person walks for 1 units at 24^@ , then from that point, walks for 2.3 units at 43^@ angle. Addition of these two vectors is an example of ...

• Does not look to be vector addition

The answer is 'sequential addition of vectors' ; at the end of the first vector, the second vector starts and added.

Two vectors are added sequentially as given in the figure. What is the result of the addition?

• the third side of triangle
• it does not make a triangle.

Answer is 'the third side of the triangle'.

Triangular Property of vector addition: When two vectors are added, arrange the initial point of the second vector to the terminal point of the first vector. In that position, complete the triangle with the two vectors as the two sides. The third side, connecting initial point of the first vector and the terminal point of the second vector, is the sum of the two vectors.
