The Satellite is big enough to be observable by human eyes. The gravitational force on it due to Earth which is weak. So, a satellite moving at a speed of 7500 m/s can be described accurately by Classical Physics. 10.

What is classical physics used for?
Classical physics involves classical mechanics (the study of the movement of fluids and particles), thermodynamics (the study of temperature and heat transfer), and electromagnetism (the study of electricity, magnets, and electromagnetic waves).
What is considered classical physics?
Classical-physics definition Physics that does not make use of quantum mechanics or the theory of relativity. Newtonian mechanics, thermodynamics, and Maxwell’s theory of electromagnetism are all examples of classical physics.
Can classical physics be used to accurately describe a satellite moving at a speed?
Can classical physics be used to accurately describe a satellite moving at a speed of 7500 m/s? Explain why or why not. No, because the satellite is moving at a speed much smaller than the speed of the light and is not in a strong gravitational field.
What are the limitations of classical mechanics?
Summary. Classical mechanics was unable to explain certain phenomena: black body radiation, the photoelectric effect, and the stability of atoms and molecules as well as their spectra.
Which of the following is not included in classical physics?
In classical theory theories of mechanics , relativity , field theory is not included . These are the category of subject which comes under Quantum mechanics(Physics) where we study small particles and classical physics also include electromagnestism (light, heat).
What is the difference between quantum and classical physics?
Classical Physics is applicable to macroscopic particles. Quantum Physics is applicable to microscopic particles.
Are classical mechanics accurate?
Classical mechanics provides extremely accurate results when studying large objects that are not extremely massive and speeds not approaching the speed of light.
Why did classical physics fail?
Classical mechanics or Newtonian mechanics failed to explain the phenomenon like black body radiation, photoelectric effect, the temperature dependence of heat capacity of the substance.
What is the difference between modern physics and classical physics?
Answer and Explanation: Classical physics focuses on topics on a macroscopic scale; these types of issues can be studied independently and do not need the aid of the five human senses. In contrast, modern science studies the nature and behavior of particles and energy through a very sub-microscopic level.
In what sense does Einstein’s theory of relativity illustrate that physics describes fundamental aspects of our universe?
19. In what sense does Einstein’s theory of relativity illustrate that physics describes fundamental aspects of our universe? It describes how speed affects different observers’ measurements of time and space.
What are disadvantages of classical physics?
Classical physics is found to be inconsistent with Maxwell’s electrodynamics. Classical physics fails to account for wave like nature of the microscopic particles, blackbody radiation anomalous Zeeman effect fine structures in atomic spectra and photoelectric effect.
What are the three phenomena that classical physics fail to explain?
This is the trademark of “modern physics.” The failure of classical physics to explain blackbody radiation, the photoelectric effect, and the hydrogen atom ultimately demolished the foundations of classical physics.
Which of the following phenomenon could not be explained by classical mechanics?
Summary. Classical mechanics was unable to explain certain phenomena: black body radiation, the photoelectric effect, the stability of atoms and molecules as well as their spectra. Quantum mechanics, created mainly by Werner Heisenberg and Erwin Schrödinger, explained these effects.
What are the 5 branches of classical physics?
- Relativistic Physics.
- Quantum Mechanics.
- Quantum Field Theories and the Standard Model.
- Condensed Matter Physics.
Is optics a part of classical physics?
Classical Physics deals mainly with macroscopic phenomena and includes subjects like Mechanics, Electrodynamics, Optics and Thermodynamics.
Which branch of physics does not belong to classical physics?
They were the first to propound the theory of relativity and quantum mechanics. Unlike the classical branch of Physics, the branch of modern physics doesn’t consider energy and matter as different entities.
Is classical mechanics better than quantum mechanics?
Quantum Mechanics has much more complicated theories than classical mechanics (thanks to Einstein), but provides accurate results for particles of even very small sizes. Quantum Mechanics handles the wave-particle duality of atoms and molecules.
What is the difference between classical theory and quantum theory?
Classical theory and quantum theory are important theories in physical chemistry. The key difference between classical theory and quantum theory is that classical theory describes the nature of macroscopic level, whereas quantum theory describes the nature of microscopic level.
Why do we proceed towards quantum mechanics rather than classical mechanics?
Because in Quantum mechanics, we studied all physical phenomenon at MICROSCOPIC SCALES, where all the actions / role is on the Plank constant (h = 6.6*10^-34 J-s). Therefore, the Quantum Mechanics departs from the Classical mechanics, primarily at the quantum realm of atomic and subatomic length scales.
Is classical physics still useful?
Classical physics is no longer used in research — it says that mass is conserved, time is absolute, there is no laser possible, quantum levels do not exist, and the hypothesis of continuity is true. Mass is only conserved as an illusion, its value changes according to E0=mc2, and binding energy.
Why can’t classical physics explain the photoelectric effect?
According to classical physics, there should be a time delay between the time the light falls on the metal surface and the emission of the electrons. In the photoelectric effect, the kinetic energy of the ejected electron is independent of the intensity of the incident radiation and depends on the frequency.
Why does classical physics predict that atoms?
Why does classical physics predict that atoms should collapse? According to Maxwell’s theory, accelerating charged particles should radiate energy in the form of electromagnetic waves. So, according to the classical physics, an electron accelerating around a nucleus should radiate energy continuously.
Can classical physics explain the photoelectric effect?
Further research showed that the photoelectric effect represents an interaction between light and matter that cannot be explained by classical physics, which describes light as an electromagnetic wave.
What are the two topics of modern physics different from classical physics?
In general, classical physics can be said to deal with topics on the macroscopic scale, that is on a scale that can be studied with the largely unaided five human senses. Modern physics, in contrast, concerns the nature and behavior of particles and energy at the sub-microscopic level.
