Newton's Laws were dependent on an absolute convention of time such that two observers would always agree as to when a given amount of time has passed in reference to physical events. As such, his Second Law (force equals mass times acceleration) allows for a force to be applied to an object forever, allowing for continual acceleration and infinite speed.
Einstein's Theory of Relativity did away with these simplistic notions by claiming that time is relative to the observer's speed such that the faster that you are moving, the slower time appears to be moving. While Newton allowed for never ending acceleration to infinite velocity, Einstein capped velocity at a constant, the speed of light(3*108 m/s). This does not mean that that the force stops working once you reach this speed, but rather that you are always approaching but not reaching it. The closer you get to the speed of light, the less a force will actually increase change your velocity.
In addition, under Newtonian physics, mass and energy were related but distinct quantities, under Special Relativity, they are actually the same as described by the famous equation E=mc2. One way to think of this is that as an object goes faster and gains more energy, it is also gaining more mass, so the same force will cause it to accelerate less and less.
Despite how poorly Newtonian Laws describe the world as compared to Einstein's, they still have their place. Special Relativity only has a significant impact at speeds near the speed of light. As long as you are far away from such speeds, Newtonian Laws provide a sufficient enough model. They may not be as accurate, but the equations are so much more simple that the loss of exactness can be excused.
What else can I help you with?
Does fusion violate the law of conservation of matter?
No, fusion does not violate the law of conservation of matter. In fusion reactions, the total mass of the reactants is equal to the total mass of the products, as mass is converted into energy according to Einstein's famous equation, Emc2.
Which law states that energy can be neither created nor destroyed?
The law that states energy cannot be created or destroyed is the first law of thermodynamics, also known as the law of energy conservation. It explains that energy can only be converted from one form to another, but the total amount remains constant within a closed system.
The law of conservation of energy states that when one form of energy is converted to another?
The law of conservation of energy says that energy is neither created nor destroyed only changed. It works hand in hand with the law of conservation of matter, because matter can be converted to energy and vice versa.
Is the principle that the amount of a physical substance remains the same even if its physical appearance changes?
The principle behind the statement is the law of conservation of energy, which states that;"Energy can neither be created nor be destroyed. It can only be transformed from one form to the other."Hence, irrespective of being a physical or a chemical change, total amount of energy in the initial stage is always equal to the total amount of energy after the change.
What law of chemistry supports this conclusion?
The law of conservation of mass supports this conclusion, stating that matter cannot be created or destroyed in a chemical reaction. This means the total mass of the products formed in a reaction must equal the total mass of the reactants.
How was the law of conservation of mass determined?
The law of conservation of mass states that in an isolated system, energy is neither created nor destroyed. It was first described by Antoine Lavoisier in 1789 and was later amended by Einstein in the Law of Conservation of Mass-Energy.
What is Einstein exception of the law of conservation of energy?
The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. However, Einstein's theory of relativity introduced the concept of mass-energy equivalence (E=mc^2), which asserts that mass and energy are interchangeable. This means that in certain situations, mass can be converted into energy and vice versa, challenging the classical notion of energy conservation.
How did Albert Einstein's theory of relativity change the law conservation of energy?
It made it less efficient and stated that it was more difficult to convert the thermal energy.
Why law of conservation of mass should better be called as law of conservation of mass and energy?
Because energy can be converted into mass and vice versa. Thus, while the mass of a system is not conserved in a particular process, the mass and energy of a closed system is always conserved.
How does Einsteins equation Emc2 support the law of conservation of energy?
If you consider mass and energy to be equivalent and interchangeable, it does not conflict with the law of conservation of energy. E=mc2 states that energy is mass and mass is energy, so it does not disprove the law of conservation of energy.
How did Albert Einstein's theory of relativity change the law of conservation of energy?
Einstein's theory of relativity did not change the law of conservation of energy. Instead, it expanded our understanding of energy conservation in situations involving high speeds or strong gravitational fields. It introduced the concept of mass-energy equivalence, encapsulated in the famous equation E=mc^2.
Law that states that energy cannot be created or destroyed?
The law that states energy cannot be created or destroyed is the First Law of Thermodynamics. It is also known as the Law of Conservation of Energy, which states that energy can only change forms or be transferred from one system to another.
What is the Conservation Law that states that Mass and Energy coexist as one?
The law you are referring to is the law of conservation of mass-energy, which states that mass and energy are interchangeable and can be converted into each other. This principle is derived from Albert Einstein's famous equation E=mc^2, where E represents energy, m represents mass, and c represents the speed of light in a vacuum.
Of thermodynamics is a restatement of the law of conservation?
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
What law of the scientific rule states that energy cannot be created or destroyed?
The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. This principle is a fundamental concept in physics and applies to all isolated systems.
Does fusion violate the law of conservation of matter?
No, fusion does not violate the law of conservation of matter. In fusion reactions, the total mass of the reactants is equal to the total mass of the products, as mass is converted into energy according to Einstein's famous equation, Emc2.
What is th law of energy called?
the law of conservation of energy
