This document defines key concepts related to thrust, pressure, and buoyancy. It begins by explaining that thrust is the force acting perpendicularly on a surface, while pressure is the thrust acting on a unit area of the surface. It then discusses how a thumb applies less pressure than a drawing pin due to differences in surface area. The document later defines pressure in terms of thrust and explains that buoyant force is the upward force exerted on an object immersed in a liquid. In closing, it defines density as the mass of a substance per unit volume.

In the fascinating realm of science, understanding the concepts of force and pressure is akin to unlocking the secrets behind the interactions that govern the physical world. As we embark on the exploration of these fundamental principles, we delve into the very essence of how objects move, interact, and respond to external influences. Force, often described as a mysterious push or pull, guides the motion of objects and lies at the heart of numerous phenomena. Similarly, pressure, the result of force distributed over an area, weaves its influence through the properties of fluids and solid structures.

In this lesson, students will learn how gravity & friction can take affect on the simple things we do everyday of our lives. Learn the 3 main types of friction, & air resistance, plus a few examples. Finally, learn about terminal velocity & get a basic introduction to magnetic & electric forces with a slight distinction for buoyancy & density.
This PPT Is made by Rehet Kaur Bhatia 8D And Is made with a lot of hardwork and Peace and it is not to copy . About the chapter The topic of Force and Pressure is one of the important concepts in science. It is very important to grasp every bit of this chapter as they are basics for all your future endeavours.
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.

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.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
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.

Thrust and pressure complete ppt
1. The force acting perpendicularly on a
surface is called thrust.
The thrust/force acting on unit area of
the surface is called pressure.
SI
unit of thrust is Newton.(N)
SI unit of pressure is Pascal.(Pa)
Let’s know more about thrust and
pressure.
2. If we push hard on a piece of wood with our thumb, the
thumb doesn’t go into the wood But if we push a
drawing pin into the wood with the same force of our
thumb, the drawing pin goes into the wood.
Our thumb doesn’t go into the wood because the force of
thumb is falling on a large area of the wood due to which
the ‘force/area’(pressure)on the wood is small .Whereas
in the case of drawing pin the area of pin falling on
wood is small therefore the pressure is more and pin
goes into the wood.
Pressure is the force acting on a unit area of the
object.
3. We have just defined pressure in terms
of force. Pressure can also be defined in
terms of another term called ‘thrust’.
The force acting on a body
perpendicularly to its surface is
called thrust.
Actually, thrust is the total force acting
on the surface of a body.

6. When an obj. is placed in a liquid, the
liq. exerts an ‘upward force’ on it .
Ex. when a piece of cork is held below
the surface of water by applying the force
of our thumb and then released, the cork
immediately rises to the surface. It
appears as if some upward force is
exerted by water on the cork which pushes
it to the surface.
7. When
an object is immersed in a
liquid, it experiences an upward force.
This upward force is called buoyant
force. Thus the upward force acting
on an object immersed in a liquid is
called buoyant force(upthrust)
8. When a solid object is immersed in a
liquid, an upward force (upthrust) is
experienced which is equal to the weight
of liquid displaced by the object.
In other words:
Buoyant force(upthrust)
Weight of
acting on an obj.
= liquid displaced
by that obj.
9. Some substances appear to be heavy
whereas others are light. For ex., iron is
heavier than aluminium and water is
heavier than alcohol. In physics we
describe the lightness or heavyness of
different substances by using the word
density. The density of substance is
defined as mass of the substance per unit
volume.
Density =mass of the substance
volume of the substance

11. I got a wonderful knowledge by making
this power point presentation as I get to
know more about
thrust, pressure, density, archimede’s
principle, etc.
I am very thankful to my IT sir and
science mam.
Thanks
