Motion refers to the way objects move, with some objects moving in a straight line, others moving in a circular motion, and some moving back and forth. Different objects like trains, fans, and swings all exhibit different types of motion, whether it be moving in a straight line, circular motion, or a back and forth pattern. Motion describes how everything around us, from large objects to small, moves in some way.

What is motion and its types
Objects move by changing their position or location over time. There are several types of motion including up and down, straight line, round and round, zigzag, and back and forth motions as seen in examples like a seesaw moving up and down, an object moving in a straight line, a merry-go-round moving in circles, and a swing moving back and forth.
How do things move ppt (3)
The document discusses different aspects of motion including that motion refers to something that is moving, objects can move at different speeds, and things may move in straight, curved, circular or zigzag paths. It also reviews key ideas like how to determine if one object is moving faster than another and different ways that speed and motion are defined.
Motion and its types
This document discusses and defines different types of motion. It begins by defining motion as a change in an object's position over time and notes that motion is always observed relative to a reference point. The main types of motion discussed are translatory motion (straight or curved), circular motion, oscillatory motion, and periodic motion. Translatory motion includes rectilinear and curvilinear types. Circular motion includes revolution and rotary motion. Oscillatory motion involves moving back and forth around a fixed point. Periodic motion repeats at regular intervals. Examples are given of objects that exhibit multiple types of motion simultaneously, such as a frisbee or sewing machine.
Types of motion
This document discusses different types of motion. It defines motion as a change in an object's position over time and notes that motion is always observed relative to a reference point. It then outlines the main types of motion as translatory, circular, random, oscillatory, vibratory, and periodic motion. Translatory motion is described as uniform motion in a straight line and can be rectilinear or curvilinear. Circular motion involves moving around a fixed axis, with examples given of revolution and rotatory motion. Several everyday objects and actions demonstrating multiple types of motion are provided.
What Is Motion
An object is in motion when its position is continuously changing relative to a reference point as observed. There are four general types of motion: linear, angular, general, and projectile. Linear motion involves uninterrupted movement in a straight line and is defined by its speed and direction, or velocity.

Motion(position and velocity)
This document discusses different types of motion including:
- Motion is defined as a change in an object's position over time.
- Position is relative to an origin point and can be positive or negative.
- Types of motion include rectilinear, circular, and periodic motion.
- Velocity refers to an object's speed and direction of motion.
2 rotational kinematics
This document defines rigid body rotation about a fixed axis and discusses rotational kinematics. It explains that a rigid body has a fixed size and shape, and its particles maintain constant relative positions during rotation. Rotational kinematics equations are provided for angular velocity, acceleration, period, frequency, and how linear acceleration varies by distance from the axis of rotation. An example problem calculates linear acceleration on a flywheel rim and revolutions completed over time.

Why does it seems that the sun move
The document discusses the motion of the Earth and how it causes day and night as well as apparent motion of the sun. It explains that the Earth rotates on its axis every 24 hours, which causes one side of the Earth to face the sun while the other side faces away, creating day and night. It also discusses how the Earth revolves around the sun over the course of 365 days.

All living things go through life cycles that involve different stages of development. The butterfly's life cycle has four main stages: egg, caterpillar, pupa, and adult butterfly. As a caterpillar, it eats leaves and grows quickly before forming a pupa and undergoing transformation inside until emerging as a young butterfly and finally a mature adult butterfly that can lay new eggs.
How can a simple machine reduce force
Simple machines make work easier by changing the amount or direction of force needed. There are six basic types of simple machines: the lever, pulley, wheel and axle, inclined plane, screw, and wedge. Compound machines combine two or more simple machines; examples include scissors, bicycles, and wheelbarrows.
Push and pull
This document discusses how forces like pushes and pulls cause motion by either moving things away (push) or bringing them closer (pull). It defines any push or pull that moves an object as a force. The document encourages the reader to have a wonderful day.
How does soil affect living things
The document discusses the formation and composition of soil. It explains that soil is formed over long periods of time through the weathering and breakdown of rocks and the decomposition of dead plants and animals. The soil is made up of weathered rocks, humus from decomposed materials, and minerals. It has distinct layers with varying properties including the topsoil, subsoil, and bedrock below. Different types of soil like sand, silt, and clay are determined by the size of particles. Loam is an ideal soil made of a mixture of these. The document emphasizes the importance of protecting soil as a vital natural resource.
How do we use air & water
This document discusses different types of water resources and how water is treated and distributed for human use. It explains that there are two main types of water - fresh water found in rivers, lakes, glaciers etc. and salt water found in oceans. It then outlines several key steps in treating water from rivers and lakes, such as allowing solids to settle, filtering through layers of sand and gravel, adding chemicals to kill harmful organisms, and pumping the clean water for distribution.

Natural disasters and diseases can change environments and affect living organisms. Floods occur when heavy rain falls in a short period, covering land with water, while droughts are long periods without rain that can dry up rivers and lakes, increasing wildfire risks that damage plant and animal habitats. Diseases from mold, bacteria, and mildew also easily spread in environments and harm living things, with one infected tree having the potential to destroy an entire forest.
Plants needs
Plants need five things to survive and grow: oxygen from the air, water, nutrients found in soil, space to grow freely, and sunlight. Fruits were once living parts of plants but become non-living when picked after ripening.
Adaptation
Organisms adapt traits that help them survive in their environments. Some examples of adaptations include camouflage, mimicry, nocturnal behavior, hibernation, and migration. Camouflage allows animals to blend into their surroundings and hide from predators or to ambush prey. Mimicry enables some animals to resemble other organisms for protection. Nocturnal habits, hibernation, and migration are ways animals adapt to changes or shortages in their environments like weather changes or lack of food sources. Plants also exhibit adaptations like deep roots that help them survive in difficult conditions.
Volume
Liquids and gases take the shape of their container, unlike solids which do not. Volume is defined as the space occupied by matter, and can be measured using tools like measuring cups. Common units for measuring volume include liters and milliliters.
How do ecosystems compare
The document compares different ecosystems by describing their climates and key characteristics. Tropical rainforests have hot, wet climates all year and contain the greatest diversity of plants and animals. Temperate forests' climates change with warm summers and cold winters, and they receive less rain than rainforests. Wetlands are covered in water most of the year, found along rivers and coasts, and help absorb flood waters and cleanse dirty water. Oceans are the largest ecosystem and most living things inhabit the sunlit, shallow areas near the surface.
Food chains and food webs
Food chains and food webs show how energy passes from one organism to another as they eat each other. A food chain tracks the flow of energy starting with a plant that gets its energy from the sun, then to an animal that eats the plant, then another animal that eats the first animal. A food web is more complex, showing that organisms can be part of multiple food chains as some animals eat different plants and other animals.
Herbivores, carnivores and omnivores
This document discusses three categories of animals based on their diets: herbivores, which eat only plants; carnivores, which eat only meat; and omnivores, which eat both plants and meat. Herbivores include deer, rabbits, elephants, turtles, monkeys and giraffes. Carnivores include lions, crocodiles, snakes and eagles. Omnivores include bears, raccoons, pigs, and humans.
Ecosystem
An ecosystem is a place where living and non-living things interact, and can exist in various environments from wet to dry and small to large. In an ecosystem, living things depend on each other and non-living things like water, soil and sunlight. Producers like plants make their own food through photosynthesis, while consumers like animals obtain food by eating other organisms, and decomposers like worms break down dead plants and animals and return nutrients to the soil.
Habitat 180115095217
This document discusses habitats and the different animals that live in each one. It explains that a habitat provides all the needs for animals to survive, including food, water and shelter. It then identifies the five main habitats as ocean, forest, desert, grasslands, and Antarctica, and provides some example animals for each one. The habitats differ in their characteristics such as being wet or dry, hot or cold, containing trees, grass or snow.
Frog life cycle
The frog life cycle consists of 5 stages - eggs are laid in water, tadpoles hatch with gills and swim, tadpoles grow legs and lungs and become young frogs, young frogs resemble adult frogs and live on land, frogs undergo complete metamorphosis as each stage looks physically different.

Mechanics:- Simple and Compound Pendulum
a compound pendulum is a physical system with a more complex structure than a simple pendulum, incorporating its mass distribution and dimensions into its oscillatory motion around a fixed axis. Understanding its dynamics involves principles of rotational mechanics and the interplay between gravitational potential energy and kinetic energy. Compound pendulums are used in various scientific and engineering applications, such as seismology for measuring earthquakes, in clocks to maintain accurate timekeeping, and in mechanical systems to study oscillatory motion dynamics.

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.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid
SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

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.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

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.

Motion
- 1. Motion
- 2. Every thing around us moves in a certain way.
- 3. •The train, the fan and the swing all move in different ways.
- 4. •The way objects move is called motion
- 5. Some objects move in one direction. They move in a straight line.
- 8. Other objects move in a circular motion.
- 11. Other objects move in a back and forth motion.
