This document discusses the different types of energy including kinetic, potential, mechanical, electrical, light, sound, thermal, and chemical energy. It explains that energy can change forms but is never created or destroyed based on the law of conservation of energy. Kinetic energy depends on an object's mass and speed while potential energy depends on its position or condition. Examples are provided to illustrate how energy is transferred and transformed, such as a swinging object converting potential to kinetic energy or a car engine changing chemical energy to motion.

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.
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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
3. The seven types of energy…
•Chemical - gasoline,
•Light – sun,
•Heat – burner,
•Nuclear , sun
•Mechanical - car,
•Sound – music on the radio,
•Electrical - lightning
4. Kinetic energy:
It’s the energy an object has due to motion
Example:
A moving bowling ball has energy that causes
the pins to fall .
This energy is called kinetic energy.
Kinetic Energy
5. The sky diver has kinetic energy
A ball kicked by a football
player has a kinetic energy
6. Mass, Speed and Kinetic Energy
• All moving objects have kinetic energy.
• Not all moving objects have the same amount of kinetic
energy.
• The amount of kinetic energy an object has depends on
the mass and the speed of the object
7.
8. Imagine those two rocks are rolling down the hillside with the
same speed.
Which one will have more kinetic energy?
Which one will cause more damage if they hit something at the
bottom?
The larger rock could cause more damage because it has larger
mass and has more kinetic energy than the smaller rock
9. Kinetic energy also depends on speed .
The faster object has more speed and has
more kinetic energy
10. Transferring kinetic energy
Kinetic energy could be transferred from one object to another when they
collide .
•The bowling ball does not touch all the pins but
it can knock them down with one roll .
•The bowling ball transfer kinetic energy to few
pins.
•The pins will transfer this kinetic energy to each
other and knock them down
11. •A transfer of kinetic energy
takes place when dominos fall.
•When you tap the first domino
you give it a kinetic energy
•Then the domino will fall into
the next one and the kinetic
energy will be transferred from
one domino to another
12. This skater has no
kinetic energy as she’s
standing at the top of
the hill and not
moving.
As the skater moves down , she is
moving faster and her kinetic energy
increases.
13. • Gravity pulls the skater down the hill.
• If the skater was standing at the bottom
of the hill, gravity wouldn’t start her
moving.
• When the skater is at the top of the hill,
she has a form of energy called
Potential energy
14. Potential Energy
•It’s the energy that is stored because of an object’s
position.
•The Higher an object is lifted above earth, the greater is
it’s potential energy
17. When you throw a
ball upwards it is
moving the fastest
so it has maximum
kinetic energy
As the ball moves
upward , it slows
down and stops
for an instant
As the ball moves
downward it
speeds up and the
potential energy is
transferred into
kinetic energy
21. Water at the top of the dam has
potential energy.
When water falls downwards
the potential energy changes
into kinetic energy
The kinetic energy
in the moving
water spins the
generators and
that’ll produce
electrical energy
22. KE and PE
• In many situations, there is a conversion between
potential and kinetic energy.
• The total amount of potential and kinetic energy in a
system is called the mechanical energy
• Mechanical energy = PE + KE
23. Mechanical Energy
•The mechanical energy does not change because the loss
in potential energy is simply transferred into kinetic
energy.
•The energy in the system remains constant!!
24. Mechanical Energy
The energy of movement.
This energy includes both
kinetic energy (motion) and
potential (stored) energy
25. Mechanical Energy
• Mechanical energy is due to the position and
motion of the object.
• What happens to the mechanical energy of
an apple as it falls from a tree?
26. Mechanical Energy
•As the apple falls to the ground, its height decreases.
Therefore, its PE decreases.
•The potential energy is not lost… it is converted into
kinetic energy as the velocity of the apple increases.
•What happens to the mechanical energy?
27. Swinging Along
•Think about the changes in energy when you are on
a swing…
•At what point do you have the most potential
energy?
•At what point do you have the most kinetic energy?
•What happens to the mechanical energy?
34. The Law of Conservation of
Energy
• The Law of Conservation of Energy states that energy
cannot be created or destroyed.
• The big picture… the total energy in the universe
remains constant.
35. Energy in Your Body
•Even the energy converted in your body follows
the law of conservation of energy.
•Chemical potential energy is transferred to kinetic
energy that allows your body to move!!
36. Calories…
• A Calorie (C) is a unit to measure energy in foods.
• 1 Calorie is equal to about 4,184 Joules.
• A person uses about:
• 55 Calories while sleeping for 1 hour
• 210 Calories while walking for 1 hour
• 850 Calories while running for 1 hour
37. Changing forms of Energy
• An example of transforming chemical energy is a car engine.
Chemical potential energy in gasoline is transformed into kinetic
energy of the car as it moves!!
38. •But how? If I stop pumping while I’m swinging,
I stop!! So, where’s the energy?
