This document discusses concepts related to motion including position, relative and absolute position, distance and displacement, speed and velocity, uniform and non-uniform motion, and uniformly accelerated motion. It defines key terms and concepts and provides examples to illustrate them. Position can be relative or absolute depending on the reference point used. Distance refers to the total path travelled, while displacement refers to the net or direct distance between two points. Speed is the rate of change of distance and velocity is the rate of change of displacement, making velocity a vector quantity. Uniform motion involves equal distances in equal times while non-uniform motion does not. Uniformly accelerated motion follows three equations of motion and has constant acceleration.

A Strategic Approach: GenAI in EducationPeter 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.

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
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.

3. POSITION
a b c d
• Suppose four a,b,c,d are seating in a
row equidistant from their neighbors
from left to right as shown
• Position of b with respect to
• a is immediate right
• c is immediate left
• d is second to the left
• Thus position is relative which varies
according to the reference point.
Left to right
4. Relative and Absolute Position
In the figure position of B with respect to A is AB in
East
Respect to C is CB North East.
• Thus position of a particular point can vary with
different points
• This is known as Relative Position .
• But in order to consider all points in one frame we
need to consider one point as a absolute referral
point an position of all other points with respect to
that point will be their
Absolute Position.
For example consider O as a absolute point then
position of all other points with respect to O will be
their absolute position for B is OB in North East.
Similarly A is OA North West and So On.
A B

Note :- 1. We Can take any point as absolute according to our convenience.
2. Direction as well as distance both is required to know ones position.
5. Illustrative Problem
• Questions:
1. What is the position of E with respect to D?
2. What is the position of O with respect to B?
3. What is the position of B with respect to E?
4. Find the absolute position of all points Considering O as absolute

6. .Concept of Rest and Motion
• Rest : A body is said to be in rest if its position does not vary with respect
to a given referral point as time passes.
• Motion: A body is said to be in motion if there is a continues change in its
position with respect to a given referral as time passes.
• Concept of rest and motion is related to referral change in position so a
single object can be at rest or motion same time with different referral
points.
• If we consider a single object as referral point and consider it as rest, as a
absolute point any object which is at rest with respect to that point is
considered at rest and same case with motion.
• In general we consider Earth as absolute point considering it at rest,
Although It is in motion with respect to Sun and other planets

8. SCALER AND VECTOR
l
l
l
AB is a line segment of
length l. AB has no
specified direction.
AB is a Scalar with
magnitude l
Also AB=BA
BA is a directed line
segment directed from B to
A. The length of BA is l that
is its magnitude is l. Thus
BA is a vector
AB is a directed line
segment directed from A to
B. The length of AB is l that
is its magnitude is l. Thus
AB is a vector
Note :- Vector BA is not equal to Vector AB as their directions are
different although they are equal in magnitude. For two vectors to be
equal both direction and magnitude should be equal.
Since the both vectors are equal in magnitude but just opposite in
directions. We can write vectorAB= -VectorBA
9. Distance And Displacement
Distance Displacement
The actual path covered during motion of
a body
The Change in position made during
motion of a body is known as
displacement
It is needed not to be the Shortest path
between two points
It is the shortest path between initial and
final position
It is the Scaler quantity as It does not
have any particular direction
It is a vector quantity as it is always
directed.
10. Illustrative Examples: A
B c
In the figure there can be various paths, but the
shortest path denotes actual change in position from
Initial point A to final point B which we call as
displacement.
11. Illustrative Example:
A B
x= 𝜋𝑟
𝑑 = 2𝑟
C
If path taken between A and B
is through arc it is
Displacement is
Suppose a boy running on the track , he starts from A and after completing one round his
distance is 2𝜋r
But his position remains same thus displacement is zero.
12. Concept of Rate:
.Rate is defined as ratio of change in two quantities
.Rate is of two types :-
.Average Rate of quantity A with respect to B
net change in Anet change in B
.Instantaneous Rate is rate at an Instant that is for very short interval of
time.
.Speed, Velocity and Acceleration are examples of Rate.
13. Speed and Velocity
• Average speed = total distance travelled/total time taken
• Instant speed = speed during a very small interval of time
• Average Velocity= Net Displacement /total time taken
• Instant velocity= velocity during a very small interval of time
• Velocity is related to displacement and thus is a vector quantity.
14. Acceleration
• Acceleration = Rate of change of velocity with respect to time
• Same as velocity there is a concept of Instant and average
acceleration
• Acceleration is a vector quantity.
• Acceleration is related to change in velocity. Therefor change of
velocity in terms of magnitude or direction both can be regarded as
accelerated motion.
In this case, the direction of velocity is keep on
changing, but the magnitude is constant. Such kind of
motion is also an example of accelerated motion.

A Graph is a pictorial representation which denotes relation between two
quantities.
In general we take X axis as Independent quantity for example we take time as X
axis as time is keep on going at its own rate independent of any other factor.
16. Concept of Slope in Graph:
• Slope of any graph represents its rate.
Linear Graph: constant Rate
o
Y
X
Ax+By+C=0
Y=(-C-Ax)/B= -C/B-Ax/B= Mx+c
Here M is the slope of Graph M=-A/B and c is Y Intercept.
This is the graph of linear Equation in which we represent how y
varies with respect to x. Thus slope is constant.
(0,c)
y2
y1
x2
x1
y2-y1
X2-x1
In this case slope M=(y2-y1)/(x2-x1)
which is constant through out.
Considering distance as Y axis and time
as X axis we came to know slope is
speed. M represents Average Speed
between two points.

In this diagram, motion of three objects A,B and C is shown.
We can see they have different speeds
The speed is slope of graph which is represented by angle made
By graph on time axis.
Slope =tan 𝜃
Roughly in this case we can say since
Speed of c is greater than B which is greater than of A
𝜃3 > 𝜃2 > 𝜃1

19. Distance Time Graph:
• Considering Motion in Straight Line:
Situation 1:
A person moving from his house consider it point A. He travels in a straight road for 5 second
with a constant Speed of 1m/s for 4seconds and reaches B. He stops their for 5 second and again
started moving in same direction for 4 seconds and reaches point C.

Graph showing Distance Time Relation according to situation 1
Note:
• In this case
• Total distance travelled = 8m
• Total time taken= 12second
• Average speed= total distance/total time
= 8m/12sec=0.67m/sec
• Total position displaced=total displacement=8m
• Average velocity=0.67m/sec from A to C
20. Position Time Graph:
• Situation 2:
Consider an object is moving in
straight direction. It starts from

direction for 1second. Then
take pause for 1 second, then
moves 4m in same direction for
2 seconds, then it rests for 2
