Force is a push or pull exerted by one body onto another that can change an object's motion or physical properties. There are three laws of motion: inertia, acceleration, and interaction. Forces include gravitational, electromagnetic, strong nuclear, and weak nuclear. Aristotle believed objects naturally remain at rest while Galileo concluded objects naturally continue their state of motion.

force and laws of Motion
Forces are pushes or pulls that cause motion or changes in motion. A force cannot be seen directly but its effects can be felt or observed. Forces can stretch, push, pull, lift, twist, or press on objects. Forces can be balanced, where opposing forces cancel each other out, or unbalanced, where a greater net force produces motion. To move a stationary object requires an unbalanced force greater than the opposing friction force, and any unbalanced force acting on a body will cause it to change its motion.
Force and laws of motion
This document discusses forces and Newton's laws of motion. It defines force and describes the different effects forces can have, such as moving, stopping, changing the speed or direction of motion of an object. It also discusses balanced and unbalanced forces. Balanced forces do not result in a change in motion, while unbalanced forces do. Newton's three laws of motion are introduced, including his first law about inertia, his second law relating force and acceleration, and his third law of equal and opposite reaction. The concepts of momentum and the law of conservation of momentum are also covered.
Newton;S Third Law
Newton's third law of motion states that for every action, there is an equal and opposite reaction. Whenever two objects interact, they apply forces to each other that are equal in magnitude but opposite in direction. Examples of action-reaction force pairs include a fish pushing water backwards to move forward through the water, and a bird pushing air downwards to be pushed upwards and fly. Newton's third law characterizes the nature of forces between interacting objects, regardless of their mass or acceleration.
physics
Newton's three laws of motion describe the relationship between an object and the forces acting upon it, and how it responds:
1. An object at rest stays at rest or an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external 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.

This document provides an overview of physics concepts including force, motion, and Newton's laws of motion. It discusses how force causes motion by speeding up or slowing down objects. There are different types of forces including gravity and friction. Newton's first law states that an object at rest or in motion stays that way unless acted on by an external force. The second law explains that acceleration depends on net force and mass. Newton's third law establishes that for every action force there is an equal and opposite reaction force. The document lists sources used to compile the information.

The document discusses different types of forces including magnetic, gravitational, contact, and non-contact forces. It explains that forces can help change the position of an object, start or stop motion, and change an object's direction. Internal forces do not contribute to motion while external forces can cause stationary objects to move. Balanced forces occur when equal forces act in opposite directions, while unbalanced forces are responsible for changes in motion as stated in Newton's first law of motion.
What are Forces???
Forces cause changes in an object's motion by pushing or pulling on objects. There are many types of forces including mass, weight, gravity, balanced forces, unbalanced forces, and air resistance. Mass is a measure of an object's inertia while weight is the force of gravity acting on an object's mass. Balanced forces do not cause changes in motion, while unbalanced forces result in acceleration or deceleration.

A force is anything that can cause an object to change its motion, speed, direction, or shape. There are four types of forces: contact forces that require touching an object like friction; non-contact forces like magnetism that act over a distance; balanced forces where multiple forces cancel each other out; and unbalanced forces where no cancellation occurs and there is a net force on the object. Examples of each type of force are given.

Force
Force is defined as an influence that causes an object to undergo a change in motion. There are two types of forces: contact forces, which require direct physical contact between objects, and action-at-a-distance forces like gravity and magnetism that do not require contact. Newton's second law states that 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. Forces can change the motion of objects by accelerating or retarding them, bring objects to rest, or produce internal stresses in objects. Common forces include applied, gravitational, normal, frictional, air resistance, tension

3 connecting motion with force
Force can be a push or pull that either changes or does not change an object's motion depending on whether the net force is balanced or unbalanced. Unbalanced forces will cause changes to an object's velocity due to inertia, the tendency of objects to resist changes in motion, with more inertia for objects with greater mass. Isaac Newton's first law of motion states that objects at rest will stay at rest and moving objects will stay in motion with constant velocity unless acted upon by an unbalanced force, such as friction between surfaces.

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 the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the direction of the net force. The third law states that for every action, there is an equal and opposite reaction. Conservation of momentum states that in a closed system, the total momentum of interacting objects remains constant.
Simple pendulum, rigid statics, stress and
The document discusses rigid bodies and the different types of stress that can be applied to objects. It explains that a rigid body is one that maintains all dimensions regardless of applied forces. The three main types of stress are tensile stress from stretching or compressing, bulk stress from changing volume with surface forces, and shear stress from tangential twisting forces. Tensile stress subjects every part of an object to tension. The amount an object stretches under tensile stress is called tensile strain, which Hooke's law states is directly proportional to the applied stress.
All about Forces
Forces can be categorized in several ways. They can be concurrent if they intersect at a single point, or non-concurrent if they act in opposite directions along the same line. Forces are also classified as balanced if they are equal in magnitude but opposite in direction, causing no net force, or unbalanced if they cause an object to change its state of motion. Contact forces act at the point of physical contact between objects, while non-contact forces act through a field such as gravity, magnetism, or electricity without direct contact.

It explains that an object at rest will remain at rest, and an object in motion will remain in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Inertia is defined as an object's resistance to changes in its motion. Examples are given of inertia of motion, like a fan continuing to spin after being turned off, and inertia of rest, like a vehicle needing force to pull another vehicle at the start.

Laws of motion2
The document discusses several laws of motion. It defines weight as the force of an object due to gravity, given by the equation w = mg, where m is the object's mass and g is the acceleration due to gravity. Mass and weight are proportional but not the same, as mass is constant while weight varies depending on location. Friction is defined as a force that opposes motion between surfaces, and depends on the roughness of the surfaces and force pushing them together.
Power point
The document discusses different types of forces including contact and non-contact forces, internal and external forces, and balanced and unbalanced forces. A force is defined as an influence that can cause a stationary body to be set in motion or change the speed or direction of a moving body. Contact forces require touching an object while non-contact forces act without touching. Internal forces are exerted from within a body and external forces are exerted from outside a body. Balanced forces have a net resultant of zero while unbalanced forces do not have a net resultant of zero.

La realización de un trabajo se relaciona con el consumo de energía, ya que la energía es la capacidad para realizar un trabajo (cuando un sistema realiza un trabajo sobre otro le transfiere energía).
Así, los conceptos de trabajo y energía aparecen identificados no sólo en las teorías físicas, sino también en el lenguaje coloquial. Dichos conceptos se fundamentan en las Leyes de Newton.
(1) newtons law of motion
Newton's three laws of motion are summarized as follows:
1) 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.
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.
Physics 3rd w11
This document discusses Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. It provides examples of acting and reacting force pairs, such as a rocket engine producing thrust by ejecting exhaust gases downward, which in turn exert an equal upward force on the rocket. Another example given is a person pushing on a skateboard, which causes the skateboard to accelerate forward and the person backward. The document also notes that physical contact is not required for action-reaction pairs, as seen in gravitational forces between objects like Earth and the Moon.
Newtons laws powerpoint new.ppt
Sir Isaac Newton discovered the three laws of motion that describe how objects move. The first law states that objects at rest will stay at rest and objects in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force. The second law states that force equals mass times acceleration. The third law states that for every action there is an equal and opposite reaction.

Statics is the study of bodies at rest or in constant motion. It involves idealizations like treating bodies as particles with mass but negligible size, or as rigid bodies that do not deform under load. Forces are also assumed to act at concentrated points. Key concepts include Newton's three laws of motion, which describe how unbalanced forces cause acceleration. Mass is a measure of matter that does not change in different locations, while weight refers to gravitational attraction that depends on elevation. The document outlines fundamental mechanics quantities like length, time, mass and force, and different systems of units - with the newton as a derived unit in the SI system.
Dynamics ib physics
This document provides an overview of force and dynamics concepts. It defines dynamics as the branch of mechanics dealing with the causes of motion. Key topics covered include forces and their effects, free body diagrams, Newton's laws of motion, momentum and its conservation, impulse, different types of forces including gravity, drag, friction, tension, and spring forces. It also discusses work, power, energy, and their transformations. Force is defined as what can change an object's state of motion. Dynamics principles are applied to examples like a man on a sloping table and collisions.
Motion
1. A force is required to change the motion of an object. 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 external force.
2. The Second Law states that the rate of change of momentum is directly proportional to the applied force. Force equals mass times acceleration. Impulse is equal to the change in momentum caused by a force applied over time.
3. The Third Law states that for every action there is an equal and opposite reaction. Forces always occur in pairs between interacting objects.
Blog ppt
A force is anything that can cause an object to change its motion, speed, direction, or shape. There are four types of forces: contact forces that require touching an object like friction; non-contact forces like magnetism that act over a distance; balanced forces where multiple forces cancel each other out; and unbalanced forces where no cancellation occurs and there is a net force on the object. Examples of each type of force are given.
Forces
Forces can be pushes, pulls, or a combination of both. There are two main types of forces - contact forces, which occur when objects touch, and non-contact forces, which occur over a distance. Contact forces include frictional forces from objects sliding against each other and muscular forces from human and animal muscles. Non-contact forces include gravitational forces, magnetic forces, and electrostatic forces. A force is any interaction that, when unopposed, will change the motion of an object.
Newton's Laws
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.
2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force.
3) For every action, there is an equal and opposite reaction.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Presented at June 6-7 Texas Alliance of Groundwater Districts Business MeetingThe debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Force
- 1. FORCE Is a push or pull exerted by another body to another Three Laws of Motion Law of inertia – A bodyat rest will remain at rest. A bodywhen in motion will continue to move with constant velocity unless acted upon an unbalanced external force. Law of Acceleration – Forceis equal to mass times acceleration (F=ma) Law of Interaction – When bodyA exerts a force in bodyB, bodyB exerts an equal but oppositeforce on bodyA. Action and reaction forces act on two different bodies and will not cancel each other. You cannot touch without being touched. Forceis a push or pull exerted by one bodyon another body. It affects the state of motion of the body. The application of force may also change the size and shape of the body. Fundamental Forces Gravitational force – is responsible for weights of the bodies on Earth as well as for the motion of the planets. Electromagnetic force – is an attractive or repulsive force between charged bodies. Strong nuclear force – holds the constituents of the nucleus together. Weak nuclear force – plays a role in the radioactive decay of some nuclei. Aristotle vs Galileo Aristotle considered that the natural state of a bodyis to remain at rest and a force is needed to act on a bodyfor it to move and keep it moving. He added: velocity of the object is proportional to the force applied. Galileo concluded that the natural tendency of a moving object is to continue moving and no force is required to keep it moving.
