Notes 3.3
Newton's 3rd law states that for every action, there is an equal and opposite reaction. Momentum is the product of an object's mass and velocity. The law of conservation of momentum states that the total momentum of a system remains constant if no external forces act on it. An example calculation shows how to determine the velocity of a ball thrown in the opposite direction of a moving skateboarder using the law of conservation of momentum.
Test ch# 6 &;7
This document contains 8 questions from physics chapters 6 and 7 about gravitational force, acceleration due to gravity on Mars, centripetal acceleration, conditions of equilibrium, and terms related to torque, couple, center of gravity, and equilibrium. The questions calculate gravitational force between lead balls and a hydrogen atom, acceleration due to gravity at different heights and on Mars, and how centripetal acceleration changes with speed, radius, and mass. It also asks to state conditions of equilibrium, explain terms related to torque, couple, center of gravity, and give an example of states of equilibrium.
Notes 3.2
Gravity is a force that depends on mass and accelerates objects. It creates a force called weight between objects due to their masses. The law of universal gravitation states that there is an attractive force between any two masses or objects in the universe whose strength depends on their masses and the distance between them. Friction is a force that opposes motion and works to slow objects down. There are different types of friction including sliding, rolling, air, and viscous friction. Centripetal force is an inward force that pulls an object traveling in a curved path towards the center to maintain its circular motion.
Newtons laws of_motion - 2nd law
The document discusses Newton's second law of motion, which states that the net force on an object is equal to its mass times its acceleration (F=ma). It provides an example calculation of using the formula to find the net force required to accelerate a 1400 kg car. It also defines that one newton is the force needed to accelerate 1 kg of mass by 1 m/s2. Gravity and its relationship to the second law is discussed, where gravitational force Fg equals mass times gravitational acceleration of 9.8 m/s2. Several example problems are provided to check understanding of applying the second law.
Mass for high school students
The Presentation is about the fundamental physical quantity Mass.
The presentation is motivated by my son back from school asked me "if weight is a force, and the unit of force is Newton, why aren't we buying potatoes in Newtons but in Kgs.
I didn't answer this question in my presentation. But, I facilitated students to find the answer themselves.
Newton
Newton's Laws describe the relationship between forces and motion. The First Law describes inertia and how objects at rest or in motion remain so unless acted on by an unbalanced force. The Second Law states that acceleration depends on mass and net force, and can be calculated as acceleration equals net force divided by mass. The Third Law describes that when one object exerts a force on another, the second object exerts an equal but opposite force back on the first.
Opportunities for students
The document discusses three proposed research projects:
1) Studying quantum phases such as supersolidity and quantum glass in ultra-cold atoms confined in optical lattices, to support future experiments.
2) Extending diagrammatic quantum Monte Carlo techniques to calculate properties of multi-species boson and fermion systems.
3) Investigating vector and chiral spin liquid phases in type-II multiferroic materials using computational and analytical approaches, to better understand and control their properties for applications.

The document discusses the cosmic microwave background (CMB) and what can be learned from precise measurements of it. The CMB provides information to answer fundamental questions about the universe, such as what it is made of, how old it is, and how fast it is expanding. Recent experiments like the Atacama Cosmology Telescope (ACT) have made accurate measurements of the CMB temperature and polarization, revealing the density of ordinary and dark matter, supporting inflation, and constraining the number of neutrino species and particle properties. Upgraded instruments like ACTpol aim to further improve measurements and help address open questions in cosmology and particle physics.

Newton's 1st and 2nd Laws of Motion. Force and mass are defined. Mass and weight are compared and contrasted.
Dr Jonathan Shock (UCT)
Strongly coupled field theories are difficult to analyze using traditional perturbation theory. The AdS/CFT correspondence provides a framework for studying strongly coupled field theories by relating them to a dual gravitational theory in a higher-dimensional anti-de Sitter space. In particular, type IIB string theory on AdS5 × S5 is dual to N=4 supersymmetric Yang-Mills theory in four dimensions. This duality allows questions about correlations functions in the strongly coupled field theory to be addressed by calculating them from the dual gravitational description. Tests of the duality have found precise matching between symmetries and fields on both sides of the correspondence.
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.

De Broglie
Louis De Broglie proposed in 1924 that electrons and other particles exhibit wave-like properties described by an equation relating the wavelength of a particle to its momentum. De Broglie's equation showed that all moving particles can be associated with a wavelength, and calculated wavelengths for everyday objects like cars and baseballs, though the wavelengths are too small to detect directly. The wavelength of electrons calculated using the equation could be measured using specialized equipment, providing evidence for the wave-particle duality of matter.
Relativity isu
1) The document discusses Einstein's theory of special relativity, which is based on two postulates about the laws of physics and the constant speed of light.
2) Some examples of relativity problems are presented, such as calculating time dilation between moving observers.
3) The implications of Einstein's work are discussed, including its role in enabling technologies like GPS and nuclear power. String theory is also mentioned as an attempt to unify gravity with other fundamental forces.
Quantum physics for dumies
This document summarizes a seminar presentation on quantum physics. It introduces key concepts in quantum mechanics like wave functions, Schrodinger's equation, and the observer effect. Some quantum phenomena are explained briefly, like quantum superposition, tunneling, and spin. Applications of quantum physics are discussed, including quantum computing and technologies like lasers. Sources for further learning about quantum mechanics online are also provided.
Astronomy_Scale
1) High energy astrophysics deals with simpler objects like protons, neutrons, and electrons, while astrochemistry and astrobiology consider more complex structures like molecules, stars, and living organisms.
2) The scale and energy involved separates these disciplines - high energies probe smaller, simpler structures while larger, more complex objects require less energy.
3) Astrochemistry uses spectroscopy to study the composition of stars, interstellar gas, and planetary atmospheres and determine which elements are present. Astrobiology examines the potential habitability of exoplanets and moons.
Conservation of moment
This document summarizes the concept of conservation of momentum. It defines momentum and the law of conservation of momentum, which states that the total momentum of an isolated system remains constant. It provides examples of how to apply the law, including a recoiling cannon, an inelastic collision between a bullet and block, and a student jumping off a skateboard. The document is submitted by a student as part of a physical science assignment.
Newton’s laws of motion
This document discusses Isaac Newton's three laws of motion and their applications. Newton's first law states that objects at rest stay at rest and objects in motion stay in motion unless acted on by an unbalanced force. Newton's second law establishes that force equals mass times acceleration (F=ma). Newton's third law describes that for every action there is an equal and opposite reaction. Examples are provided to demonstrate these laws, such as how gravity causes apples to fall from trees and how objects with different masses accelerate at the same rate but with different forces due to their mass.
Quantum Chromodynamics
This document provides an overview of chromodynamics and the quark model. It discusses the following key points:
- Quantum chromodynamics describes the strong force and interaction between quarks via the exchange of gluons. Quarks have a property called "color" and gluons mediate the color force.
- The quark model proposes that hadrons like baryons and mesons are composed of more fundamental particles called quarks. Early models included up, down and strange quarks.
- Additional quarks were later discovered and the color quantum number was introduced to satisfy the Pauli exclusion principle and allow different quark combinations. Color neutrality is achieved through combinations of three quarks or a quark-antiquark pair
Strong Nuclear Force and Quantum Vacuum as Gravity (FUNDAMENTAL TENSOR)
Publication at ccsenet. Gravity explained by a new theory, ‘Superconducting String Theory (SST)’, completely opposite from current field emission based and inspired on originals string theories. Strengths are decomposed to make strings behave as one-dimensional structure with universe acting as a superconductor where resistance is near 0 and the matter moves inside. Strong nuclear force, with an attraction of 10.000 Newtons is which makes space to curve, generating acceleration, more matter more acceleration. Electromagnetic moves in 8 decimals, gravity is moved to more than 30 decimals to work as a superconductor.
Quantum mechanics S5
1) Classical mechanics and Maxwell's equations can explain macroscopic phenomena but quantum mechanics is needed to explain microscopic phenomena such as atomic structure.
2) Quantum mechanics arose from the need to explain physical phenomena not accounted for by classical physics, including blackbody radiation, the photoelectric effect, atomic spectra, and specific heat of solids.
3) Experiments such as the photoelectric effect, Compton effect, diffraction of electrons demonstrated that particles have wave-like properties and waves have particle-like properties, showing the need for a new theoretical framework that incorporated wave-particle duality.
Wave mechanics
The document discusses wave-particle duality and Louis de Broglie's hypothesis that all matter has both wave-like and particle-like properties. It summarizes key experiments that supported this idea, including Davisson and Germer's 1927 experiment in which electron beams were diffracted by crystal lattices, demonstrating their wave-like behavior. The document also explains how de Broglie's hypothesis resolved issues with early atomic models by introducing the concept of electron standing waves within atoms.
Strong Nuclear Force and Quantum Vacuum (TRANSITION)
This document proposes a new theory called the Superconducting String Theory (SST) to explain gravity. The theory postulates that:
1) The universe acts as a superconductor where matter can move with near-zero resistance.
2) Strings in the universe are extremely tense and can conduct matter infinitely.
3) The strong nuclear force, carried by gluons, causes the strings to bend, generating an attractive force similar to gravity between masses. More mass results in more bending of the strings and a greater attractive force.
4) Under this theory, gravity is not a fundamental force itself but emerges from the interaction of the strong nuclear force with the superconducting strings of the universe. Some
Lecture johnson
This document discusses the Higgs particle and the searches that have been conducted to find it. It begins by explaining how particle masses are generated in the Standard Model through the Higgs mechanism. This involves the Higgs field imparting mass on particles when they interact with it. Experiments like LEP and the Tevatron have searched for the Higgs boson but have so far only found lower limits on its possible mass range. Future experiments like the LHC are expected to directly detect the Higgs if it is light, around 100-1000 GeV/c^2. Discovering the Higgs would validate the Standard Model, while not finding one would require new physics beyond the model.
Quarks
The document discusses the four fundamental particles that make up all ordinary matter - up quarks, down quarks, strange quarks, and charm quarks. Murray Gell-Mann named quarks after a line in James Joyce's book "Finnegan's Wake" and received the 1969 Nobel Prize for his work classifying elementary particles. As particle accelerators achieve higher energies, they can probe matter at finer scales and produce more massive objects via E=mc^2, leading to the discoveries of heavier quarks like bottom and top quarks.
Quantum mechanics for Engineering Students
The Quantum mechanics study material gives insight into the fundamentals of the modern theory of physics related to Heisenberg uncertainty principle, wavefunction, concepts of potential well etc.
Nuclear chemistry B Sc III-SEM-VI
The document provides an introduction to nuclear chemistry, which deals with the study of atomic nuclei and nuclear reactions. It discusses the composition of nuclei, which contain protons and neutrons. The number of protons defines the element, while the total number of protons and neutrons is the mass number. The document also summarizes two nuclear models - the nuclear shell model, which proposes protons and neutrons exist in shells, and the liquid drop model, which views the nucleus as a homogeneous drop with short-range nuclear forces. Examples of nuclear reactions like alpha-induced and proton-induced reactions are also briefly described.
Forces and motion scripted
The document provides an overview of a 50-70 minute lesson on forces and motion for 6th and 8th grade science classes, which introduces students to how unbalanced forces affect an object's motion through videos, simulations, and demonstrations. The lesson addresses state science standards while exploring concepts such as Newton's laws of motion, forces, inertia, and acceleration, highlighting contributions from scientists like Galileo and Newton. Students predict and observe how applying forces changes an object's speed or direction.
Actionreactionworksheet
This document provides instructions for students to draw and label examples of action-reaction force pairs. It includes examples of common action-reaction pairs like a hand on a flower or fist on a wall. Students are tasked with describing the reaction forces shown and drawing the corresponding arrows. They are then asked to draw their own example and label the forces at each contact point in a final example showing a scale reading the amount of force.

1st Law (Inertia):
- A car at rest stays at rest unless a force acts on it.
- A ball rolling across a table will keep rolling at the same speed and direction unless something stops it or changes its motion.
- An object in motion in outer space will stay in motion with the same speed and direction unless another force interacts with it.
2nd Law (F=ma):
- The harder you push on a heavy box, the slower it will accelerate compared to a lighter box with the same push.
- A rocket accelerates faster as it burns fuel and loses mass over time.

The document discusses Newton's three laws of motion:
1) An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force. Friction causes moving objects to slow down.
2) 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.
3) For every action, there is an equal and opposite reaction. The forces acting between two interacting objects are equal in magnitude but opposite in direction.

This document discusses Newton's law of universal gravitation. It defines the law, which states that a force of attraction exists between any two masses and this force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. It then provides three practice problems that apply this law to calculate gravitational forces between objects of different masses and distances.

Examples are provided to illustrate each law, such as friction stopping moving objects, forces needed to accelerate objects of different masses, and action-reaction force pairs that allow birds to fly and rockets to launch.
Newtons laws of_motion
Newton's three laws of motion are:
1) An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
2) 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.
3) For every action, there is an equal and opposite reaction.
Newtons law of motion
Newton's three laws of motion are summarized as follows:
1) Law of Inertia: An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
2) F=ma: Force equals mass times acceleration.
3) Action-Reaction: For every action there is an equal and opposite reaction.

Rockets internet.ppt
The document discusses Newton's second and third laws of motion and how they relate to rocket propulsion. It explains that rockets accelerate due to unbalanced forces from the ejection of exhaust particles, as per Newton's third law of action and reaction. Different rocket designs eject particles of varying mass, affecting their thrust according to the formula force equals mass times acceleration. The document provides examples of water rockets, balloon rockets, and real rockets to illustrate how thrust can be varied based on the mass and speed of exhaust particles.
Newtons laws of motion
While most people know what Newton's laws say, many people do not know what they mean (or simply do not believe what they mean).
Newton’s laws of motion
This document provides an overview of Sir Isaac Newton and his three laws of motion. It discusses that Newton was a highly influential physicist, astronomer, and mathematician born in 1643 in England. He published his most influential work Principia which described universal gravitation and his three laws of motion. The first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force. The second law states that acceleration is produced when a force acts upon a mass, directly proportional to the force and inversely proportional to the mass. The third law states that for every action there is an equal and opposite reaction.
newtons_laws_of_motion.ppt
This document provides information about Newton's Three Laws of Motion:
1) Newton's First Law of Motion (Law of Inertia) states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Friction is given as an example of a force that can cause an object in motion to slow down and stop.
2) Newton's Second Law of Motion (Law of Acceleration) states that the net force on an object equals its mass times its acceleration (F=ma). Examples are given to demonstrate how acceleration depends on mass and net force.
3) Newton's Third Law of Motion

The document contains questions and answers about concepts related to gravity, projectiles, and Newton's laws of motion. Some of the key points covered include:
- Satellites need to be above the atmosphere to avoid air resistance.
- The maximum projectile distance is achieved at a 45 degree angle.
- Gravity accelerates objects at 9.8 m/s^2 near Earth's surface.
- Newton's three laws of motion explain forces like inertia, acceleration, and action-reaction pairs between objects in contact.
Lesson 2 Motion and Conservation Laws.ppt
This document provides an overview of motion and conservation laws. It begins by explaining Aristotle's conception of motion as natural or violent, then Galileo's rejection of the idea that a force is needed to maintain motion. It then covers Newton's three laws of motion and uses them to explain why objects fall at the same rate regardless of mass. The document also discusses conservation of mass, energy, and momentum. It provides examples of applying the laws of conservation to collisions and gravitational interactions.

Electromagnet Project
This document provides instructions for an electromagnet project that is due the week of April 11th and will count as a quiz. Students are instructed to wrap electric wire tightly around a nail to create an electromagnet, connecting the wire to a battery through a switch. When the switch is turned on, the electromagnet should be able to pick up small metal clips or objects, with more loops or higher battery voltage creating a stronger magnetic field.
Magnetism notes
Hans Christian Oersted discovered in the 1800s that an electric current produces a magnetic field, demonstrating the relationship between electricity and magnetism. An electromagnet can be constructed by placing a coil of wire around a piece of iron, and its magnetism can be controlled by increasing or decreasing the voltage or number of wire loops. Electromagnets are used in many electric devices, including motors, generators, magnetic storage, and industrial lifting magnets.
Magnetism
Magnetism is a force that acts at a distance and is caused by magnetic poles and fields. Magnets have north and south poles, and like poles repel while opposite poles attract. Some materials like iron, nickel, cobalt, and steel are magnetic due to their atomic composition. The Earth itself acts like a giant bar magnet, and its magnetic field is what allows compasses to work and is caused by the motion of its iron-nickel core.
Electric Circuit Project
Students are to work in teams of 3 to design and build an electric circuit project using materials like wire, light bulbs, batteries and switches that is due the week of April 11 and will count as a quiz, with 80% of the grade based on the circuit working and 20% on the diagram. The circuit can be either series or parallel and students are encouraged to get creative with designs like a lighthouse, volcano, or traffic lights.
Electricity basic facts
This document provides an overview of basic electricity concepts. It explains that electric charge allows objects to exert force without touching via an electric field. Atoms have protons with positive charge and electrons with negative charge, and opposite charges attract while like charges repel. Charge can be transferred by contact or induction. Some animals use electricity to hunt. Conductors allow charge movement while insulators do not. Current is the flow of charge. Voltage, resistance, and current are important measurements defined by Ohm's Law. Batteries produce current which needs a closed circuit to flow through components like switches, lights, and motors. Circuits can be constructed in series or parallel configurations.
