1. Speed is the ratio of distance covered to time taken and has no direction, while velocity is the ratio of displacement to time and has direction.
2. Average speed is the total distance divided by total time over varying speeds, while average velocity is the total displacement divided by total time.
3. Constant velocity means a body covers equal displacements in equal times, while variable velocity means unequal displacements over equal times.

this project is basically based "motion", the way it's directly or indirectly linked to us. Viewing this power point presentation will enable you to study as a whole in descriptive way.In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance (scalar), velocity, acceleration, time and speed.Motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame n If the position of a body is not changing with the time with respect to a given frame of reference the body is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. Momentum is a quantity which is used for measuring motion of an object. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in an isolated system (one not affected by external forces) does not change with time, as described by the law of conservation of momentum.

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.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Module # 03
Speed & Velocity
Speed
Speed is the ratio of total distance covered to the total time taken.
Speed is usually denoted by V. If distance is denoted by S and
time by t, then, it is written as:
V = S/t
Units of speed are meter per second or kilo meter per hour.
Speed has no direction. It is a scalar quantity. The speedometer
of a moving car measures speed of the car.
The terms speed and velocity are commonly used
interchangeably, but, by definition, there is an important difference
between these two terms. Speed is always determined by
distance and velocity is determined by displacement. Hence,
speed is a scalar quantity and velocity is a vector quantity.
Average Speed
The average speed is defined as the total distance covered
divided by the total time with varying speeds.
If average speed is denoted by Vav, then
2. 2
Total distance covered S
Vav = ------------------------------ = ------
Total time t
Uniform Speed or Constant Speed
If the body covers equal distances in equal intervals of time, its
motion is said to be uniform speed.
The speed is said to be constant or uniform, if the moving body
covers equal distances in equal intervals of time however small.
Velocity
The rate of change of displacement is called velocity. It is a vector
quantity. If the change in displacement is ΔS, taking place in time
Δt, then, the velocity is given as
Displacement ΔS
Velocity = V = -------------------- = -------------
Time Δt
The units of velocity are m/s or km/h in a particular direction.
3. 3
Constant Velocity
If a body covers equal displacements in equal intervals of time,
then, the body moves with constant velocity. The body moving
with constant velocity has no acceleration and we say that the
motion of the body is uniform motion.
Instantaneous Velocity
The velocity of a body for very short interval of time (instant) is
called the instantaneous velocity. A very short interval of time
means that Δt is too short that Δt tends to zero (or Δt approaches
to zero). The velocity of a body for any instant is called the
instantaneous velocity and it is denoted as Vinst.
Therefore,
ΔS
Instantaneous Velocity = Vins. = Lim -------------
Δt0 Δt
Average Velocity
If a body is moving with variable velocity, then, to find average
velocity, we divide the total displacement by total time.
4. 4
Therefore,
Total Displacement ΔS
Average Velocity = Vaverage = ---------------------------- = ------------
Total time Δt
Uniform Velocity
If the velocity is uniform, both average and instantaneous
velocities are equal. The displacement - time graph of a body
moving with uniform velocity will be a straight line.
The velocity is said to be constant or uniform, if the moving body
covers equal displacements in equal intervals of time, however
small.
Variable Velocity or Non-Uniform Velocity
If a body covers unequal displacements in equal intervals of time,
then, the body will be moving with variable velocity. The body has
non-uniform velocity. The body may have positive or negative
acceleration. A body falling freely has variable velocity.
Thus, if the displacements covered by a body in equal intervals of
time are not equal, then, the body is said to move with variable
velocity i.e. its speed or direction or both are changing e.g.
velocity of a body moving in a circle.
5. 5
Terminal Velocity
It is the maximum velocity VT at which the net acceleration
becomes zero.
OR
Terminal velocity is that maximum velocity at which the weight of
a body becomes equal to the drag force.
Escape Velocity
It is defined as the initial velocity given to a body on the surface of
the earth which will enable the body to escape out of the influence
of the earth's gravitational field. Thus, the body will be able to go
up to infinity.
Angular Velocity
The angular displacement per second is called angular velocity. It
is dented by . Therefore,
Angular displacement
Angular Velocity = = --------------------------------- = -----------
time t
6. 6
Direction of Angular Velocity
The angular velocity is a vector quantity. Its direction is given by
right hand rule.
Units of Angular Velocity
The SI units of angular velocity are radian per second or written
as rads-1
.
Other Units are revolution per second or written as revs-1
and
degrees per second or written as degs-1
.
Instantaneous Angular Velocity
If the angular velocity is not uniform during the interval of time 't',
then, we can find the instantaneous angular velocity at any instant
which is defined as the angular displacement in a very small
interval of time.
OR
The angular velocity at a particular instant is called instantaneous
angular velocity.
7. 7
Average Angular Velocity
The average angular displacement per second is called average
angular velocity. It is dented by .
Thus,
Average angular displacement ()
Average Angular Velocity = = -----------------------------------------------------------

Revolving Velocity
The velocity with which artificial satellites revolve around the earth
is called revolving velocity.
