Kinetic energy is the energy of motion and is calculated as K = 1/2 mv^2, where m is mass and v is velocity. Doubling speed quadruples kinetic energy, and tripling speed multiplies it by nine. The SI unit for kinetic, potential, and all other types of energy is the Joule. Potential energy depends on mass, gravitational field strength, and height. The total energy before and after an energy transformation will be equal according to the law of conservation of energy. Work is the product of force and displacement and can be positive, negative, or zero depending on the direction of force relative to motion.

Work is defined as a force acting on an object and moving it through a displacement. It is calculated as work equals force times distance (W=Fd). The SI unit for work is the joule. Work can be positive when force and displacement are in the same direction, negative when they are in opposite directions, and zero when the force is perpendicular to displacement. Power is the rate of doing work and is calculated as work divided by time. Energy is the ability to do work and its SI unit is also the joule.

Work Power and Energy

Work is defined as a force acting on an object and moving it through a displacement. It is calculated as work = force x displacement. The SI unit of work is the joule. Work can be positive when force and displacement are in the same direction, zero when they are perpendicular, and negative when opposite. Power is the rate of doing work and is calculated as power = work/time, with the unit watt equal to joule/second. Energy is the ability to do work and has the unit joule.

Buoyancy.ppt

Buoyancy and pressure in fluids are discussed. Objects experience an upward buoyant force when submerged in fluids due to higher pressure at deeper levels pushing up on the bottom of the object. Archimedes' principle states that the buoyant force equals the weight of fluid displaced by the object. The buoyant force can be calculated by subtracting the weight of the object in water from its weight in air.

Acceleration

This document discusses acceleration and how it relates to changes in an object's velocity over time. It defines acceleration as the rate of change of velocity, whether that means changing speed or direction. Acceleration is calculated by finding the change in velocity divided by the time taken. Positive acceleration increases velocity while negative acceleration decreases velocity. The constant acceleration due to gravity on Earth is approximately 10 m/s2. Free falling objects experience this acceleration and will fall at increasing speeds over time if air resistance is negligible. Galileo was one of the first scientists to study acceleration from gravity by rolling objects down inclined planes and observing their increasing speed over time.

Waves

Waves are disturbances that transfer energy through a medium. They are caused by vibrations in the medium and can be transverse, longitudinal, or a combination. Key properties of waves include amplitude, wavelength, frequency, and speed. Waves interact with each other and surfaces through reflection, refraction, diffraction, interference, and can form standing waves through the combination of incoming and reflected waves.

Universal forces

This document discusses key concepts about the forces that hold our universe together. It defines facts, laws, hypotheses and theories, with theories being the highest level explanations supported by evidence. Atoms are made up of electrons, protons and neutrons. The four fundamental forces are gravity, electromagnetism, strong nuclear force, and weak nuclear force. Gravity is the attraction between masses. Electromagnetism includes both electrical charges and magnetism. The strong nuclear force binds protons in an atom's nucleus. The weak nuclear force is responsible for neutron decay.

Static electricity

Static electricity is the buildup of electric charges on the surface of objects. It was discovered in 600 BC by Thales of Miletos who observed that rubbing amber with fur caused the amber to attract feathers due to static charge. Benjamin Franklin's kite experiment in the 1740s demonstrated that lightning is a form of electricity. Static charge is generated through friction, conduction, or induction. Objects can become positively or negatively charged by gaining or losing electrons. Coulomb's Law from 1785 describes the electrostatic force of attraction or repulsion between two point charges, directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Sound

Sound is a form of energy that travels in waves from a vibrating object. It can travel through solids, liquids, and gases in the form of compression waves. The ear detects sound waves and transmits signals to the brain. Properties of sound waves include frequency, wavelength, amplitude, and pitch. The speed of sound depends on the medium and temperature, being fastest in solids and slowest in gases. Reflection and refraction of sound waves results in phenomena like echoes and resonance. Doppler effect changes the perceived frequency of a sound based on the motion of its source.

Projectile motion

Projectile motion involves objects moving through the air without propulsion. It has constant horizontal velocity but constant downward acceleration. The trajectory is a parabolic curve. Key equations given relate the total time, horizontal range, and maximum height to the initial velocity and launch angle using kinematic equations that treat horizontal and vertical motions independently.

Power

Power is defined as the rate at which work is done or energy is consumed, measured in Watts (J/s). Two examples are provided: (1) A Big Mac contains 2,000,000 J of energy, which could power a 60W light bulb for about 9 hours. (2) Lifter A exerted 1000N of force over 0.5 seconds to lift a barbell 0.8m, resulting in a power output of 1600W, while Lifter B took 0.75 seconds for 800W of power. Power calculations are demonstrated for cycling and stair stepping exercises.

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.

Newtons laws of_motion - 1st law

This document summarizes Newton's three laws of motion. It explains the first law of inertia, which states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force. It provides examples using eggs to illustrate the concepts of balanced and unbalanced forces and how they relate to an object changing or maintaining its motion. Safety tips are also given related to wearing seatbelts based on the first law of inertia.

Motion2

This document discusses speed, velocity, and distance-time graphs. It defines speed as distance divided by time and uses examples to calculate speed. A distance-time graph that is a straight line indicates constant speed, while a curved graph shows acceleration. A speed-time graph can reveal if an object is maintaining a steady velocity, slowing down, or speeding up based on whether the line is horizontal, slanting down, or slanting up.

Motion

This document discusses frames of reference and the differences between motion, distance, and displacement. It provides examples to illustrate key points. The most common frame of reference is the Earth. Motion is defined as a change in position relative to a frame of reference. Distance is the actual length traveled along a path, while displacement is the straight line distance and direction between the start and end points. Vectors contain both magnitude and direction, while scalars contain only magnitude.

Metrics

The document discusses various measurements in the metric system including length, volume, mass, temperature, and density. It explains that the metric system uses base units like meters, liters, and grams along with prefixes like kilo, centi, and milli which are powers of ten. Converting between units involves moving the decimal place right or left based on multiplying or dividing by ten. The Celsius scale uses 0°C for freezing and 100°C for boiling water. Density is calculated by dividing an object's mass by its volume.

Magnetism

Magnets have been known for centuries, with the Chinese and Greeks aware of their unusual properties. The ancient Greeks used a stone called magnetite that always pointed in the same direction, which later helped with navigation. William Gilbert proposed in 1600 that the Earth itself acts as a magnet with magnetic poles. Magnets have north and south poles and attract objects made of iron. The magnetic field can magnetize other materials and cause charged particles to spiral around magnetic field lines.

Light em&bigbang

The document discusses the electromagnetic spectrum and the Big Bang theory. It explains that electromagnetic radiation consists of photons with different wavelengths and energies. The farther away objects are observed, the farther back in time we see them due to the finite speed of light. Measurements of the cosmic microwave background radiation provide evidence that the universe began in a hot, dense state around 13.7 billion years ago and has been expanding and cooling ever since, as predicted by the Big Bang theory.

Gravity and motion

This document discusses gravity and its effects. It explains that Isaac Newton first hypothesized that gravity causes apples and the moon to fall toward Earth. Gravity is a force that attracts all objects and depends on the masses and distance between objects. Newton's law of universal gravitation states that gravitational force is proportional to the product of masses and inversely proportional to the distance between them. Gravity and inertia combine to keep objects like Earth and the moon in orbit. Mass is the amount of matter in an object, while weight is the gravitational force on the object.

Friction

Friction is a force that opposes the relative motion between two surfaces in contact. The amount of friction depends on the type of surfaces and the force pressing them together. Friction can be beneficial by allowing us to grip objects, but also harmful as it causes wear and reduces efficiency. Rough surfaces have more friction than smooth surfaces due to more contact points. Friction converts kinetic energy into thermal energy, and lubricants can reduce friction to improve machine efficiency.

Free body diagrams

Free body diagrams show the relative magnitude and direction of all forces acting upon an object by isolating it from its surroundings. The document provides examples of free body diagrams for the Statue of Liberty, a sitting gorilla, a wooden swing, a bungee jumper's bucket, a traffic light, and the pin at point A of a truss bridge. Forces are shown as vectors with arrows indicating direction and labels providing magnitudes. Diagrams for static systems will sum the vertical and horizontal forces to zero, indicating equilibrium.

Electricity

This document contains a series of lessons on electrical concepts:
Lesson 1 discusses static electricity and defines key terms like protons, electrons, and charge. Lesson 2 explains the difference between open and closed circuits. Lesson 3 reviews a lesson on conductors and insulators. Lesson 4 discusses parallel and series circuits and provides examples of each. Interactive quizzes are included throughout to help reinforce the concepts covered in each lesson.

Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Embracing Deep Variability For Reproducibility and Replicability

Embracing Deep Variability For Reproducibility and ReplicabilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS

The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.
