Teaching about energy choices is supported by 6 key concepts:

Energy from atoms The process that produces the heat in a nuclear plant is the fissioning or splitting of uranium atoms. – A free PowerPoint PPT presentation (displayed as a Flash slide show) on - id: 66a2fd-Mzg5Z. 4 Chapter 7. Nuclear Energy NEL 7381PhyCH07pp002-057.indd 4 Posted 8.18.10 in 1st pass folder 8/18/10 3:33:18 PM are said to be in their ground state: the electrons are all at the lowest possible energy.

7.1 Economic security is impacted by energy choices. Individuals and society continually make energy choices that have economic consequences. These consequences come in the form of monetary cost in general and in the form of price fluctuation and instability specifically.

7.2 National security is impacted by energy choices. The security of a nation is dependent, in part, on the sources of that nation's energy supplies. For example, a nation that has diverse sources of energy that come mostly from within its borders is more secure than a nation largely dependent on foreign energy supplies.
7.3 Environmental quality is impacted by energy choices. Energy choices made by humans have environmental consequences. The quality of life of humans and other organisms on Earth can be significantly affected by these consequences.
7.4 Increasing demand for and limited supplies of fossil fuels affects quality of life. Fossil fuels provide the vast majority of the world's energy. Fossil fuel supplies are limited. If society has not transitioned to sources of energy that are renewable before depleting Earth's fossil fuel supplies, it will find itself in a situation where energy demand far exceeds energy supply. This situation will have many social and economic consequences.
7.5 Access to energy resources affects quality of life. Access to energy resources, or lack thereof, affects human health, access to education, socioeconomic status, gender equality, global partnerships, and the environment.
7.6 Some populations are more vulnerable to impacts of energy choices than others. Energy decisions have economic, social, and environmental consequences. Poor, marginalized, or underdeveloped populations can most benefit from positive consequences and are the most susceptible to negative consequences.

There are direct connections between energy use and quality of life

Energy has both positive and negative impacts on societies. Access to abundant, affordable, secure, safe, and clean energy is beneficial for humans. But energy extraction, transportation, and use can have negative consequences to the health, environment, and economics of a society. Moreover, relying on imported energy can create vulnerabilities to a nation's security. The impacts of energy decisions are not equal for all people. Poor or marginalized societies are more likely to suffer negative consequences of energy decisions because they have a reduced capacity for adaptation and they may lack negotiating power compared to wealthier societies. Therefore, vulnerable populations can benefit greatly from improvements in energy accessibility, safety, or affordability.
This topic also raises the fundamental problem that the world is strongly dependent on a finite supply of fossil fuels. As demand increases and supply becomes scarce, the problem becomes more acute, with potentially severe economic and social consequences. A large-scale transition away from fossil energy poses a great challenge for society.

Energy is a global, multicultural topic

Students can expand their thinking beyond their own personal experiences with energy and consider ways in which energy can impact the economics, security, environment, and health of other societies. Energy supplies are traded globally and the effects of energy use have worldwide consequences, so students can appreciate the expansive reach of energy issues. Students, particularly younger students, may not have considered how their own experiences with energy are vastly different from students their own age in different countries. Students will need to be exposed to ideas, values, and case studies from other cultures in order to appreciate how energy choices differ around the world. This broad-view approach is particularly helpful when considering negotiations and cooperation between nations as we tackle climate change and sustainable energy challenges.

Similar to Energy Principle 6, these ideas may result in students confronting the impacts of American energy choices on the rest of the world. This is particularly poignant as developing economies strive to achieve a quality of life that is more similar to ours, which is resulting in sharply increasing consumption of energy in developing nations. Educators can aim to broaden students' worldviews while also preventing feelings of guilt or helplessness.

Bringing these ideas into your classroom

A key goal within this topic is for students to gain a sense of how energy use affects quality of life for other societies. Activities can be structured to build on the personal approach used in Energy Principle 6 and extend this to gain perspective for how energy choices influence life both at home and around the world. Compared to many children across the globe, American students enjoy a high standard of living and use more energy per capita than most. Many Americans are also removed from the immediate effects of energy extraction, transportation, and waste disposal. Case studies, videos, and personal accounts from those whose lives are challenged by energy use can be engaging ways for students to connect with a perspective from another culture.

Middle school students can examine 'a day in the life' scenarios for children their own age in different cultures. How much energy do children use in Canada, Kenya, and Japan? What differences in culture and lifestyle contribute to different energy use patterns? How do climate, transportation, food, and standard of living affect energy consumption? And how does the availability of energy affect the quality of life?

High school students are more likely to have traveled to other cultures or met people from around the world, so it will be somewhat easier for them to appreciate how energy might affect quality of life. Exchange students can offer insights to energy use in their home countries. High school students can also take field trips to local energy installations to visit a power plant, hydroelectric dam, or a mine. Observing the effects of energy development firsthand can help students appreciate how energy development has direct effects on the landscape.
College students can consider energy in context to geology, geography, population dynamics, economics, societal needs, and human health. The topic of energy and quality of life can be explored in many types of courses. College students can work with data sets about energy resources, use, and prices around the globe. A case study approach will allow students to consider many facets of energy in a particular culture.

Hello students, how are you, I think you are good, God bless you always. I am your physics teacher and Blogger. This blog is made just only for you.

I want to tell you something, please read this before proceeding to the blog/website


Physics is one of the most interesting subjects which is filled with numerous engaging concepts.

Physics is an important subject not only for the board exam but also for various competitive exams. Both engineering and medical aspirants need to prepare for the subject. Engineering and medical entrance exams – JEE Main and NEET – are both based on the NCERT syllabus of Class 11th and 12th. So, the detailed NCERT Class 11th and 12th syllabus of Physics will help engineering and medical aspirants as well.

First, keep in mind that, physics is a very easy subject, we ourselves make it difficult. Many people facing the problems that they are not able to solve numerical very well. This is because you do not have in-depth theoretical knowledge. You cannot make solve numerical without through understanding fundamentals.

And keeping this in mind, I have created this blog


Chapter 7nuclear Energy And Societymr.'s Learning Website Page

for you.

This blog has been made keeping in mind your exam and N.C.E.R.T syllabus, so that you can get the most benefit.

Radha Krishna (Hindi: राधा कृष्ण) is an Hindi TV Serial on Star Bharat channel. Sumedh Mudgalkar/ Himanshu Soni as Lord Krishna and Mallika Singh/Shivya Pathania as Radha are in. Mounica is a south Indianfilm and televisionactress. Her big break was in MAATV's show Radha Madhu as Madhu (Madhulika). The story of Radha Madhu is based on YaddanapudiSulochana Rani and the dialogues were made by Azad and were edited by P.A. The story is about two strangers, Radha and Madhu who meet under extraordinary circumstances and their lives get. Radha madhu serial story.

Below are some instructions that the students should read and follow. Believe me, to create this blog, I had to close my coaching classes for few days so that I could make this blog as soon as possible.

This blog covers all the syllabus of N.C.E.R.T.


♦ Often, it had been seen that some students whose mathematics is not good, they do not have a good hold in physics, because we know that “Mathematics is the language of physics“.

That is, why the students should understand mathematics very well.

♦ And it had also been seen that some students do not take class 11th seriously, due to this when they go to class 12th, they faced many problems. This is because most of the basic concept of physics was covered in the 11th standard, like mechanics, this is the topic of on which almost the entire physics concept is based on, so I would like to request all of the students that they should take class 11th syllabus (Physics) seriously.

When you read this blog, go through each topic thoroughly and if there is any doubt, then immediately ask your teacher or text me in the comment section, I will try my best to answer your queries and concerns.

♦ It had also been seen that when a student faces difficulty in any topic then they try to skip that topic. This will make it very difficult to understand physics, because almost all the topics of physics are related to each other, so please, try to understand the topic instead of skipping, it won’t benefits you at all.

As, I am putting the content for this blog bit slowly, it will take some time to cover the entire syllabus. Whatever topic I have been inserted, I’ll put that at the beginning of this page, so that you do not have have to face navigation problem. Here, I am just covering the 12th standard first, then after, I will cover the 11th standard very soon.


Making notes is essential. The act of writing or recording notes helps motor, visual, and auditory recall. This makes the subject easier to remember.

Because of all the years you understand physics very well and resolve numerical. That is why during the exam time it is your-notes that help you the most.

Many students found making notes a troublesome act. With proper notes, in hand during exams time would save a lot of time and effort and no doubt it would help you to crake the exam easily. More importantly, it makes learning more fun. A good example of an integral study habit that students must have to make notes.

All you have to do is that I am making the notes for you, just note down and go through it.

Believe me, this is the best notes for you. This will cover all class 11th and 12th syllabus of physics.


This blog ” SIMPLE PHYSICS NOTES” gives a better platform with which you can easily understand any topic of physics,

There are a few things to keep in mind before starting this blog.

1. This blog is for those who want good notes of physics.
2. This blog covers all the syllabus of N.C.E.R.T.
3. Believe it, reading this blog order Wise will make your theory part very good.
4. The first condition for making numerical is that the concept of your theory part is very good.
5. Numericals of each topic are separated and given in the last of each topic so that it is very easy to make numericals.

6. First, note the student theory on your copy, it is very important, and understand it, if there is any kind of doubt, please comment on me, otherwise understand it from your tuition faculty, then make the numericals given in the last.
7. As I write the content of this blog, I’ll put that at the beginning of the page.
8. Since it has not been long since I started this blog, I will be putting the content slowly.

THANKS, A LOT…………………….
