Newton’s 2nd law of motion!
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. Specifically, the acceleration of an object depends on the net force applied and is inversely proportional to the object's mass, such that acceleration equals net force divided by mass. Mass refers to the amount of matter in an object, while weight is the measure of gravitational force acting on the object and depends on location.
Ppt Newtons Second Law
Newton's Second Law of Motion describes the relationship between an object's mass, the net force acting upon it, and its acceleration. Specifically, it states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The equation that expresses this is Force = mass x acceleration (F=ma). According to this law, a baseball that is thrown with greater force will experience a higher acceleration than one that is tossed gently, as the greater force applied results in a greater acceleration even though their masses are the same.
Track 252
The document discusses Newton's Laws of Motion. It explains the 1st law that an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force. The 2nd law states that acceleration is produced by a force acting on a mass, and greater force is needed to accelerate objects with greater mass. The 3rd law is that for every action there is an equal and opposite reaction. It also defines linear motion as movement in a straight line from one point to another.
Newtons 2nd law of motion[1]
Sir Isaac Newton discovered the three laws of motion, including Newton's Second Law which states that the force on an object is equal to its mass times its acceleration (F=ma). Newton's Second Law proves that objects with different masses accelerating due to gravity will hit the ground with different forces, even though they accelerate at the same rate, because force depends on both mass and acceleration. The Second Law is useful for quantifying the relationship between force, mass, and acceleration for objects in motion.

Motion laws of newton 2
Newton's second law relates force, mass, and acceleration. It states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object's mass. Several problems are provided as examples applying Newton's second law to calculate acceleration given force and mass or vice versa.
Momentum and impulse
The document discusses momentum, impulse, and Newton's laws of motion. It defines momentum as the product of an object's mass and velocity, and explains that the net force acting on an object is equal to the rate of change of its momentum according to Newton's second law. It also describes the principle of conservation of momentum in isolated systems, and defines elastic and inelastic collisions. Finally, it states that impulse is equal to the change in an object's momentum, where impulse is defined as the product of net force and the time interval for which it acts.
F= Ma
Newton's second law states that acceleration is directly proportional to force and inversely proportional to mass. It also specifies that an object accelerates in the direction of the applied force. Force is calculated using the formula F=ma, where F is force in newtons, m is mass in kilograms, and a is acceleration in meters per second squared. Centripetal force is any force directed toward the center of an object's circular path, such as the force exerted by a skater's partner to keep them moving in a circle.
Newton's law of motion
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.

Examples are provided to illustrate each law, including how friction causes an object in motion to come to rest due to an unbalanced force. Check questions are included to test understanding of applying the second law calculations.
Force and Acceleration
The document discusses Newton's Second Law of Motion, which states that the acceleration of an object depends on the net force acting on it and its mass. It can be expressed by the equation Force = mass x acceleration (F=ma). The document provides examples of using the equation to calculate force, mass, or acceleration when two of the three values are known.
Engineering mechanics
Engineering mechanics involves the study of what happens to rigid bodies and particles when forces are applied. A particle is an object that has mass but a negligible size, while a rigid body maintains a fixed shape and size. When two or more forces act on a body, they form a system of forces. Newton's laws of motion state that objects at rest stay at rest and objects in motion stay in motion unless acted on by an unbalanced force, the acceleration of an object is proportional to the net force acting on it, and for every action there is an equal and opposite reaction. Statics utilizes concepts like the triangle law of forces and polygon law of forces to resolve forces into components.
Motion and Laws of motion
1) An unbalanced external force is needed to change the motion of an object. Galileo observed that objects in motion tend to stay in motion and objects at rest tend to stay at rest, unless an external force acts upon them.
2) Newton further studied Galileo's ideas and formulated his three laws of motion. Newton's first law formalizes the idea that objects resist changes to their motion.
3) Newton's second law states that the acceleration of an object is directly proportional to the net external force acting on it, and inversely proportional to its mass. It can be expressed as: Force = Mass × Acceleration.

Forces smartboard exported
Forces can be balanced even if their magnitudes are not equal, as long as the sum of the forces in the x-direction and sum of the forces in the y-direction are both equal to zero. Forces can also be balanced if they have equal magnitudes but directions that are not opposite, as long as their directions are non-collinear. The forces shown are balanced because the net force in each direction is zero, even though the magnitudes are unequal and directions are not opposite.

It discusses key aspects of science including observation, developing hypotheses, experimentation, data collection and analysis, and conclusions. The scientific method is presented as a repeatable process for systematically investigating topics through direct and indirect observation, purpose statements, experimentation while controlling variables, quantitative data collection, and evaluating results to draw inferences.
Pressure ch3
Forces in Fluids discusses key concepts related to fluid pressure and motion. It explains that pressure is defined as force per unit area and that fluids transmit pressure equally in all directions. Hydraulic devices take advantage of this property to amplify force. Gravity causes pressure to increase with depth in fluids. Buoyancy is the upward force exerted on objects in fluids due to the weight of fluid displaced. Archimedes' principle states this buoyant force equals the weight of fluid displaced. Bernoulli's principle explains that fluid pressure decreases as speed increases.
Predator prey!
This document discusses the key concepts of a predator-prey activity including ratios and food pyramids, competition both between and within species, biomagnification, checks and balances in ecology, and adaptations for survival. It provides examples to look up about mutualism, commensalism, parasitism, and directs the reader to resources about the Isle Royale wolf-moose population study.
Mfe chapter 5 notes
This document discusses different forms of energy including mechanical, heat, chemical, electromagnetic, and nuclear energy. It defines kinetic energy as the energy of motion and potential energy as stored energy. The document explains that energy can be converted from one form to another, but the total amount of energy remains constant due to the law of conservation of energy. Understanding energy and its transformations is important for studying physics and the physical sciences.
Mfe chapter 4 notes
This document discusses work, power, simple machines, and compound machines. It defines work as a force acting through a distance, and power as the rate at which work is done. Six simple machines are described: inclined planes, wedges, screws, levers, pulleys, and wheels and axles. Compound machines combine two or more simple machines to make work easier by changing the input force, distance, or direction of force. The mechanical advantage of machines allows work to be done with less input force.
Magnetism
The document discusses magnetism and magnetic domains. It provides instructions for an experiment using compasses and bar magnets to determine magnetic poles and north direction in a room by comparing results with other groups. Students are asked to explain their procedure and draw a diagram of their results from an experiment using a ring magnet and compass.
Light talk
1. Light can be modeled as rays, waves, or particles. The ray model uses lines to show the path of light, while the wave model explains phenomena like reflection and refraction.
2. Light exhibits properties of both waves and particles. In the double slit experiment, light behaves like a wave and shows interference patterns. However, experiments also show light behaving like particles called photons.
3. When light encounters different materials, it can be reflected, absorbed, or transmitted. These interactions impact the color we see. The ray model uses rules like reflection to diagram how light behaves in situations like mirrors, fibers, and periscopes.
Heat
The document discusses kinetic molecular theory and heat transfer. It explains that all matter is made of molecules that are always in motion, and their motion increases with temperature. Heat is a form of energy caused by molecular motion, and it transfers from hot to cold through conduction, convection, or radiation. Temperature is a measure of average molecular motion or energy, while heat is the total energy of that motion.
Forces
The document discusses the concept of force. It defines force as any push or pull on an object. Forces can cause acceleration by changing an object's speed or direction of motion. Balanced forces occur when forces cancel each other out, resulting in no acceleration, while unbalanced forces work together to cause acceleration. Common units for measuring force include the Newton. The document also discusses concepts such as mass, inertia, momentum, acceleration, friction, and how weight is related to mass and gravity.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
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

A Survey of Techniques for Maximizing LLM Performance
A Strategic Approach: GenAI in Education
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.

Newton's 3 laws
- 1. 1 Law of Motion st • An object will maintain its state of motion unless an outside force acts upon it. • The only way to cause acceleration is with an outside force • The “law of inertia” • The energizer bunny law
- 2. 2nd Law of Motion • Force= Mass Times Acceleration (f=ma) • Allows you to calculate force based on mass of object and how quickly (or slowly) it accelerates • Mass (kg) times Acceleration (m/s/s) gets you units of “kg m/s/s” (which defines a Newton)
- 3. 3rd law of motion • Forces come in pairs that are equal and opposite. • You can’t push something without it pushing you back • Forces NEVER act alone!
