The Law of Inertia (The 3 Laws of Motion).pptRose Alba
What is the meaning of law of inertia?
The law of inertia states that an object or mass will remain either at rest or in motion in the same direction, unless acted upon by an unbalanced force. This also means that the more massive an object is, the more difficult it is to influence its velocity.
Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.

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.

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

(1643-1726)
He was an English
physicist, mathematician,
astronomer, natural
philosopher, alchemist,
and theologian and one
of the most influential
men in human history.
4. Newton’s Laws of Motion:
LAW OF INERTIA
LAW OF ACCELERATION
LAW OF INTERACTION
6. Inertia
- the tendency of objects to resist
changes in state of motion
States of motion may be:
-At rest
-Moving with a constant velocity
-Moving with changing velocity
(Accelerating)
7. Law of Inertia
An object at rest will remain at rest
and an object in motion will remain
in motion moving with constant
velocity unless acted upon by a net
force.
8. Law of Inertia
An object at rest will remain at rest
and an object in motion will remain
in motion moving with constant
velocity unless acted upon by a net
force.
9. Law of Inertia
An object at rest will remain at rest
and an object in motion will remain
in motion moving with constant
velocity unless acted upon by a net
force.
10. Law of Inertia
An object at rest will remain at rest
and an object in motion will remain
in motion moving with constant
velocity unless acted upon by a NET
FORCE.
11. net force
- unbalanced force
balanced forces
- forces that are equal in
magnitude and opposite in
direction
equilibrium
- the state in which all forces are
balanced
12. Law of Inertia
Force, in its simplest sense, is a push
or a pull.
It can be an influence capable of
producing a change in the state of
motion of an object.
13. Law of Inertia
Types of Forces:
contact forces – forces that require
physical contact between objects
noncontact forces - forces that do
not require physical contact between
objects
14.
15. Mass and Inertia
The tendency of objects to resist
changes in state of motion varies
with mass.
A more massive object has a
greater tendency to resist changes
in its state of motion.

1. Imagine a place in the cosmos far from
all gravitational and frictional influences.
Suppose that you visit that place (just
suppose) and throw a rock. The rock will
a.gradually stop.
b.b. continue in motion in the same
direction at constant speed.

2. Mac and Tosh are arguing in the
cafeteria. Mac says that if he flings the
Jell-O with a greater speed it will have a
greater inertia. Tosh argues that inertia
does not depend upon speed, but rather
upon mass. Who do you agree with?
Explain why.

5. Ben Tooclose is being chased through
the woods by a bull moose that he was
attempting to photograph. The
enormous mass of the bull moose is
extremely intimidating. Yet, if Ben makes
a zigzag pattern through the woods, he
will be able to use the large mass of the
moose to his own advantage. Explain this
in terms of inertia and Newton's first law
of motion.
28. Law of Acceleration
The acceleration of an object as
produced by a net force is directly
proportional to the magnitude of the
net force, in the same direction as
the net force, and inversely
proportional to the mass of the
object.
30. Newton’s second law pertains to
the behavior of objects for which
all existing forces are NOT
balanced (there is acceleration).
The second law states that the
acceleration of an object is
dependent upon two variables -
the net force acting upon the
object and the mass of the object.
32. Finding Acceleration: Practice Problems
1. An applied force of 50
N is used to accelerate an
object to the right across a
frictional surface. The
object encounters 10 N of
friction. Use the diagram
to determine the normal
force, the net force, the
mass, and the acceleration
of the object. (Neglect air
resistance.)
33. Finding Acceleration: Practice Problems
2. An applied force of 20 N
is used to accelerate an
object to the right across a
frictional surface. The object
encounters 10 N of friction.
Use the diagram to
determine the normal force,
the net force, the mass, and
the acceleration of the
object. (Neglect air
resistance.)
34. Finding Acceleration: Practice Problems
3. A 5-kg object is
resting on top of a table.
Determine the force of
gravity, the normal
force, the net force, and

to move a 1500 kg car with an
acceleration of 4 m/s2
?

rice?
37. Law of Interaction
For every action force, there is
always an equal but opposite
reaction force.
38. Law of Interaction
• The action and reaction forces are
contact forces (forces acting in
contact).
• Action-reaction forces act on
different bodies.
a wall-hand system
a baseball-baseball bat system
• Forces acting are equal in magnitude .
