Why does the laws of classical physics break down as you approach the speed of light?
At speeds near the speed of light, the formulae from the Theory of Relativity show that there are discrepancies with classical physics - for example, in adding velocities. These discprepancies have been verified by many experiments.
In theory the discrepancies arise at any speed, but if the speed is much lower than the speed of light, the difference between classical physics and the more accurate Theory of Relativity is so insignificant that it can be ignored, and you can safely use the simpler formulae of classical physics.

What is classical particle?
Classical physics refers to the branch of Physics whereby energy and matter are two very different concepts. It is usually based on the theory of electromagnetic radiation and the laws of motion.
When does newtonian physics fail to explain motion correctly?
Newtonian physics fails to explain motion correctly in extreme conditions such as at speeds approaching the speed of light or in the presence of very strong gravitational fields where the effects of relativity become significant. Additionally, at the quantum level, where particles behave in ways that cannot be predicted using classical physics, Newtonian physics also breaks down.
Why can't a rocket in space accelerate to the speed of light?
A rocket cannot accelerate to the speed of light in space because as you approach the speed of light, the energy required to accelerate further increases exponentially, making it practically impossible to reach or surpass the speed of light. Additionally, as you approach the speed of light, the relativistic effects come into play, making it increasingly difficult to accelerate due to the mass increase of the object.
What atomic observation gave us the first hint that all of Newton's law didn't apply in all cases and how did this rise to Quantum physics?
The photoelectric effect was the observation that gave the first hint that Newton's laws did not apply at the atomic level. This led to the development of quantum physics because it showed that light can behave both as a wave and a particle, which could not be explained by classical physics. Quantum physics emerged to provide a more accurate description of phenomena at the atomic and subatomic levels.
Why can't an object with mass travel at the speed of light?
According to Einstein's physics, it would require an infinite amount of energy to accelerate a mass to the speed of light. Unless we invent warp drive, it ain't gonna happen. ================================== My high school physics teacher explained that it's like pushing wagon up a hill. As you get closer to the speed of light, the wagon becomes a car. As you get even closer to the speed of light, the car becomes a truck, becomes a bus, etc. E=mc^2 Mass grows as you approach the speed of light. Therefore, more energy is required to move the ever increasing mass.
Can classical physics explain the photoelectric effect?
No. To explain the photoelectric effect, you have to think of light as a particle, not a wave. The fact that light can be both a wave and a particle is part of quantum mechanics, not classical physics.
Define the major division and subdivision of physics?

What is the definition of classical physics?
Classical physics is the physics without considering quantum mechanics. This is the type of physics practiced by for example Newton (you might also come across the term Newtonian physics). General relativity is also a classical theory. The distinction is often used because quantum mechanics changed quite a bit in many fields of physics, so the term 'classical physics' allows for a clear distinction. The opposite of classical physics would be quantum physics.
What did classical physics predict would happen to the light given off by an object as its temperature increased?
Classical physics predicted that the light given off by an object would shift to shorter wavelengths and higher frequencies as its temperature increased, following the principles of blackbody radiation. This is known as Wien's displacement law.

What are the failure of classical physics related to photoelectric effect?
The classical Physcis said that waves and particles are two different components. In Quantum Physics , we know that light ( or eletromagnetic waves ) demonstrates wave-particle duality. In this case, the light behaves as a collection of particles called photons. The energy of each photon is given by hv.
According to classical physics what should happen as a filament in a light bulb gets hotter?
It should give off light of increasing energy- from red, to violet, and then into ultraviolet.This is because classical physics believed that the color of the light will correspond with the increasing of energy until it reaches ultraviolet. This is somewhat true as the color does correspond with the increasing energy but no matter how much energy there is, it will never reach ultraviolet. modern physics found that it will only stay white.

Classical physics CANNOT explain why?
There are many examples of what classical physics can not explain. (By classical physics we mean that which has its theoretical foundations before about 1900.) Quantum mechanics is absent from classical physics. Classical physics can not explain why atoms (positive nucleus attracted to surrounding electrons) is stable. Even the simplest atom, a hydrogen atom, would be unstable and the electron orbiting the proton would gradually radiate its energy and the orbit would decay. The photoelectric effect is an important historical example of the failure of classical physics. In that case, electromagnetic theory said that light was an electromagnetic wave. That was true enough but it does not account for the quantum nature of light and the characteristics that allow a photon to act like a discrete bundle of electromagnetic energy with properties like a particle. Virtually all of our understanding about the atomic structure and properties of matter depends on quantum mechanics, so the example of hydrogen is just symbolic of the need for modern physics for the entirety of our understanding about electronic properties of matter. One can choose to define classical physics to include relativity or not as one wishes, but it is fair to say that Newtonian mechanics does not explain relativistic mechanics. In particular, time dilation and length contraction are purely relativistic effects.
What is traditional physics and modern physics?
Traditional physics are more commonly called "Classical Physics" and it was created by the old giants of physicists like Newton and Galileo.Modern physics are the newer study of physics that was created by folk like Einstein and Schrodinger.The main difference is that classical physics deals in things that are relatively and easily handled by human size in terms of observation, forces and speeds. Things like the motion of baseballs, cars and planets.Modern physics deal in things that are small or fast. Time dilation due to traveling near the speed of light falls under modern physics as does the world of subatomic particles. The nature of electromagnetic radiation roughly follows the same wave math involved in classical physics, however, things get deeper when we begin to discuss the wave-particle duality of matter and light so it is more modern physics.
What are the kinds of classical physics?
The main branches of classical physics are mechanics, which includes the study of motion and forces; thermodynamics, which deals with heat and energy transfer; electromagnetism, focusing on electrical and magnetic phenomena; and optics, involving the behavior of light.
Classical physics predicted that?
Classical physics predicted that the universe operates according to deterministic laws, where the behavior of particles and systems can be precisely calculated. It also introduced concepts such as conservation of energy, momentum, and angular momentum to describe the motion and interactions of objects.
