The document defines work in physics as being done when a force causes an object to move through a displacement. It provides the mathematical formula for work as W = Fd, where W is work, F is the applied force, and d is the displacement. It also states that work is a scalar quantity and defines the SI unit of work as the joule. Examples of positive, negative, and zero work are given based on whether the force and displacement are in the same, opposite, or perpendicular directions.

We spend more time working than doing anything else in life. Yet for too many people, the experience of work is demotivating and dehumanizing.
I don’t think it has to be this way, and I’m willing to bet you don’t either.
At Google, we’ve learned a ton about what makes for an enjoyable and productive workplace. We’re not alone – lots of other companies, ranging from grocers (e.g., Wegmans) to textile companies (e.g., the Brandix Group) to Brooklyn delis (e.g., Russ & Daughters), as well as academics and scientists, have learned the same simple truth: there are straightforward things we can do to make work better.
My new book, "Work Rules!", is an attempt to bring this together and offer you practical tools to improve work, no matter what you do. Check out this visual preview of the book and visit www.workrules.net if you’d like to pick up a copy or learn more!

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
2. Q. Which agent causes or tends to cause motion in a
body?
A. It is the “force” which causes or tends to cause
motion in a body.
F
3. Q. What is force ?
A. The agent which ;
Stops or tends to stop the motion
OR
Produces or tends to produce the motion
4. Q. Which path is the shortest in the figure
shown?
A. 2nd path is the shortest one.
Q. What does the shortest path called?
A. Displacement
1st path
2nd path
A B
3rd path
5. Q. Which quantity depends upon force and
displacement?
A. Work depends upon force and displacement.
7. WORK
In general work is said to be done when
someone pushes against a brick wall
and does not able to move it
A boy studies a book for a few hours
But in Physics work is defined differently
8. WORK
Q. What is work?
A. Work is said to be done when a force acts on a
body and moves it through a certain
displacement.
F
m m
d
Work done by the Force F
10. WORK
If force is applied on a body and it moves the
body through a displacement ‘d ’, then the work 'W' is
defined by the relation
W = F. d
We have already studied scalars and vectors.
Q. What is the nature of work?
A. Work is a scalar quantity.
11. WORK
If the force makes an angle θ with the
direction of the displacement then,
We take the component of the force in the
direction of the displacement
12. WORK
Unit of work:
The SI unit of work is joule (J).
One Joule
When a force of one Newton moves a body
through a distance of one meter in the direction of
force, then the work done is equal to one joule.
13. CASES OF WORK
Positive Work
When force and displacement are in the same
direction
Then θ = 0°
W = F d cos 0°
= Fd x1
= Fd
14. CASES OF WORK
Positive Work
In this case work done is maximum and is
equal to the product of the magnitude of force
and displacement.
18. CASES OF WORK
Negative Work
When force and displacement are in the opposite
direction
Then θ = 180°
W = F d cos 180°
= F d x (-1) cos 180° = -1
W = -Fd
20. ACTIVITY
Given Data
Applied force = F = 300 N
Displacement covered by body = d = 10m
Angle between force and
displacement = θ = 60o
Work done =w =?
21. WORK
Q. What is the definition of work?
A. It is the product of displacement and component
of force along displacement.
Q. What is the unit of work?
A. The unit of work is “joule”.
22. WORK
Q. Give an example of positive work?
A. Pushing something horizontally is an example of
positive work.
Q. Give an example of negative work?
A. Lifting something vertically upwards is an example
of negative work.
23. CASES OF WORK
Q. Give an example of zero work?
A. If a person holds the pail in his hand and walks
along a level surface.
Q. Explain the given figure?
