Why is the first law called law of inertia?
the first law of motion deals with inertia. it describes about the inertia or the tendency of a body to remain in rest or uniform motion.more over, implicit in the discussion of Newton's first law is the concept of an inertial reference frame, which for the purposes of Newtonian mechanics is defined to be a reference frame in which Newton's first law holds true.
There is a class of frames of reference (called inertial frames) relative to which the motion of a particle not subject to forces is a straight line.
hence newtons first law is also called law of inertia.
Yes, Isaac is generally considered to be intelligent based on his ability to solve complex problems and demonstrate high academic achievement.
Is force based upon both mass and acceleration?
Yes, force is based on both mass and acceleration. The formula for force is F = m*a, where F is force, m is mass, and a is acceleration. This means that the force applied to an object depends on the mass of the object and the acceleration it experiences.
What is the value of a newton?
Force is expressed in Newtons
It's newtons - never capitalised, , but the abbreviation, N, *is*, because it's derived from a personal name.
The simplest example is the force due to gravity.
Strictly speaking, weight is *not* expressed in grams/kilograms/tonnes. These are measures of *mass*, and a 1 kg object will always have that mass (at ordinary speeds), whether it's on earth or out in space.
Here on earth, due to gravity, the 1 kg mass experiences a force of 1 kilogram-force.
Because the force of acceleration due to gravity is abuout 9.81 metres/second, 1 kilogram-force equates to 9.81 newtons.
My mass of around 70 kg becomes a weight of about 690 N.
How do newtons three laws of motion apply to real world situations?
Isaac Newton Isaac Newton Isaac Newton had 3 laws now we have them if we use them we can explain motions cause isaacs first law not his best law says things do what they know best if things arent moving they will stay there if things are moving they wont rest, jst a bit more on the first law that u really ought to know an outside force that is not cancelled really changes the whole show
When does newtons third law is applicable to bodies?
Newton's third law states that for every action, there is an equal and opposite reaction. It is applicable whenever a force is exerted on a body, resulting in a reaction force of equal magnitude but in the opposite direction on another body. This law is always in effect when there are interactions between two objects.
Why is there no equal and opposite reaction when you punch into the air?
When you punch the air, there is no firm object to exert an equal and opposite reaction force as described by Newton's third law of motion. The air offers minimal resistance compared to a solid object, so the force you exert dissipates quickly without a significant reaction force.
How did Isacc newton persisted?
Isaac Newton persisted through his work by staying dedicated and focused on his scientific research despite facing challenges and setbacks. He was known for his determination, perseverance, and intense work ethic, which helped him make groundbreaking discoveries in physics and mathematics.
Did Isaac Newton do Anything Wrong?
He disliked women (sorry) and had a deep hatred for laughing and apparently poetry to him was "nonsense" some people claimed that Isaac was depressed or was poisoned with Mercury which he worked with a lot. He was supposed to be a farmer but he was a terrible farmer and never worked at a farm.
I hope this helped!
No, the work done by the net force on a particle is independent of the inertial reference frame of the observer. However, the change in kinetic energy is frame-dependent due to the kinetic energy term in the relativistic energy equation.
When did Sir Isaac Newton publish the theory of gravitation?
Sir Isaac Newton published his theory of gravitation in 1687 in his famous work "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy).
What is the equation used to figure the acceleration of a 25 N force when the mass is 100 kg?
F = ma
If you know the net force and the mass, you can determine the acceleration by manipulating the equation such that a = F/m.
a = 25N/100kg = 0.25m/s2
Newton's first law, the law of inertia, states that an object will remain at rest or in uniform motion unless acted upon by an external force. It applies to objects in both motion and at rest.

He developed new mathematical models to explain fundamental particles and their interactions, particularly in the context of quantum field theory. His work has advanced our understanding of the fundamental forces of nature and paved the way for further research in particle physics.
What was Isaac Stern famous for?
Isaac Stern was a renowned violinist known for his virtuosity and passionate performances. He played a significant role in popularizing classical music and mentoring younger musicians. Stern also helped to save Carnegie Hall from demolition in the 1960s.
What happens when the same force is applied to an object?
If the object was stationery before any forces were applied it will remain stationery, and if it was moving it will remain moving but at a constant speed.
There is no resultant force so the object experiences no acceleration.
What law of motion says that an object will stay in motion unless a greater force acts in it?
This statement is based on Newton's First Law of Motion, also known as the law of inertia. It explains that an object will remain at rest or continue moving in a straight line at a constant speed unless acted upon by an external force.

Why are objects in freefall considered Weightless?
Because the object's inertial motion is equal to the gravitational acceleration.
Weight equals mass times gravitational acceleration (W=mg), so you would feel weightless, but your mass stays the same.
Newton's First Law of Motion (Law of Inertia) states that an object will remain at rest or in uniform motion unless acted upon by an external force.
How does Newtons third law apply to Croquet?
In croquet, Newton's third law applies when a player strikes their ball with the mallet. When the mallet pushes on the ball (action), the ball exerts an equal and opposite force back onto the mallet (reaction), causing the ball to move in the opposite direction. This law governs the transfer of momentum between the mallet and the ball in the game of croquet.
Who was Issac newton and what did he accomplish?
Newton's work has been said "to distinctly advance every branch of mathematics then studied".[23] His work on the subject usually referred to as fluxions or calculus, seen in a manuscript of October 1666, is now published among Newton's mathematical papers,[24] the manuscript De analysi per aequationes numero terminorum infinitas sent by Isaac Barrow to John Collins in June 1669, Barrow identified to Collins in August of that year as:[25]Mr Newton, a fellow of our College, and very young ... but of an extraordinary genius and proficiency in these things.
Newton later became involved in a dispute with Leibniz over priority in the development of infinitesimal calculus. Most modern historians believe that Newton and Leibniz developed infinitesimal calculus independently, although with very different notations. Occasionally it has been suggested that Newton published almost nothing about it until 1693, and did not give a full account until 1704, while Leibniz began publishing a full account of his methods in 1684. (Leibniz's notation and "differential Method", nowadays recognised as much more convenient notations, were adopted by continental European mathematicians, and after 1820 or so, also by British mathematicians.) Such a suggestion, however, fails to notice the content of calculus which critics of Newton's time and modern times have pointed out in Book 1 of Newton's Principia itself (published 1687) and in its forerunner manuscripts, such as De motu corporum in gyrum ("On the motion of bodies in orbit"), of 1684. The Principia is not written in the language of calculus either as we know it or as Newton's (later) 'dot' notation would write it. But his work extensively uses an infinitesimal calculus in geometric form, based on limiting values of the ratios of vanishing small quantities: in the Principia itself Newton gave demonstration of this under the name of 'the method of first and last ratios'[26] and explained why he put his expositions in this form,[27] remarking also that 'hereby the same thing is performed as by the method of indivisibles'.
Because of this, the Principia has been called "a book dense with the theory and application of the infinitesimal calculus" in modern times[28] and "lequel est presque tout de ce calcul" ('nearly all of it is of this calculus') in Newton's time.[29] His use of methods involving "one or more orders of the infinitesimally small" is present in his De motu corporum in gyrum of 1684[30] and in his papers on motion "during the two decades preceding 1684".[31]
Newton had been reluctant to publish his calculus because he feared controversy and criticism.[32] He had a very close relationship with Swiss mathematician Nicolas Fatio de Duillier, who from the beginning was impressed by Newton's gravitational theory. In 1691, Duillier planned to prepare a new version of Newton's Principia, but never finished it. However, in 1693 the relationship between the two men changed. At the time, Duillier had also exchanged several letters with Leibniz.[33]
Starting in 1699, other members of the Royal Society (of which Newton was a member) accused Leibniz of plagiarism, and the dispute broke out in full force in 1711. The Royal Society proclaimed in a study that it was Newton who was the true discoverer and labelled Leibniz a fraud. This study was cast into doubt when it was later found that Newton himself wrote the study's concluding remarks on Leibniz. Thus began the bitter controversy which marred the lives of both Newton and Leibniz until the latter's death in 1716.[34]
Newton is generally credited with the generalised binomial theorem, valid for any exponent. He discovered Newton's identities, Newton's method, classified cubic plane curves (polynomials of degree three in two variables), made substantial contributions to the theory of finite differences, and was the first to use fractional indices and to employ coordinate geometry to derive solutions to Diophantine equations. He approximated partial sums of the harmonic series by logarithms (a precursor to Euler's summation formula), and was the first to use power series with confidence and to revert power series.
He was appointed Lucasian Professor of Mathematics in 1669 on Barrow's recommendation. In that day, any fellow of Cambridge or Oxford was required to become an ordained Anglican priest. However, the terms of the Lucasian professorship required that the holder not be active in the church (presumably so as to have more time for science). Newton argued that this should exempt him from the ordination requirement, and Charles II, whose permission was needed, accepted this argument. Thus a conflict between Newton's religious views and Anglican orthodoxy was averted.[35]
When two forces act on an object in opposite directions in a closed balloon the foresc are?
When two forces act on an object in opposite directions inside a closed balloon, the forces are in equilibrium. This means that the net force on the object is zero, resulting in no acceleration of the object.
The value of the friction force will increase to match and oppose the external force up to a maximum value known as the static friction force. Once the external force exceeds the maximum static friction force, the object will begin to move, and the friction force will decrease to the kinetic friction force, which is generally lower than the maximum static friction force.
