According to the principle of mass-energy equivalence (E=mc^2), energy and mass are interchangeable. In theory, energy can be created without mass, such as in the case of virtual particles popping in and out of existence in quantum mechanics. These particles have energy but no permanent mass.
What else can I help you with?
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.
Can Matter and energy be created or destroyed?
According to the principle of conservation of mass-energy, matter and energy cannot be created or destroyed, only transformed from one form to another. This is a fundamental concept in physics known as the law of conservation of mass-energy.
Is it true that the law of conversation of mass states that in any chemical or physical change energy is not created or destroyed?
No, the law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. However, the law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
What is the KE of a 6kg mass at 4?
To calculate the kinetic energy, you need to know the speed of the mass in addition to its mass. The kinetic energy equation is KE = 0.5 * m * v^2, where m is mass and v is velocity. Without the speed of the mass, the kinetic energy cannot be determined.
Which laws states that mass cannot be created or destroyed?
Conservation of mass... but this has been slightly revised since. Now it is the conservation of energy. Mass can be converted to energy. In some chemical reactions in the early 20th century scientists observed that the mass of the reactants did not equal the mass of the products. This was ultimately resolved with Einstein's mass-energy equivalence formula, E = mc^2, where Eistein postulated that some rest mass was converted to energy. From this, we know that energy cannot be created or destroyed.
What would your world be without energy?
Mass=energy so a world without energy is a world without mass. If you don't have energy you don't have a world.
How is gravitational potential energy created?
It is created when a body of unit mass is brought from infinity to that point without acceleration.
Why can't matter be creAted from energy?
In any reaction, or process, both the amount of mass and the amount of energy remain constant. You might say that mass has energy, and energy has mass. Any mass or energy "created" during a reaction was already present previously.
This law states that energy or mass cannot be created or destroyed?
law of conservation of energy and mass
How do you increase the potential energy of a wagon without increasing its mass?
You can increase the potential energy of a wagon by lifting it to a higher elevation. This increases its gravitational potential energy without changing its mass.
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.
Can Matter and energy be created or destroyed?
According to the principle of conservation of mass-energy, matter and energy cannot be created or destroyed, only transformed from one form to another. This is a fundamental concept in physics known as the law of conservation of mass-energy.
What makes energy without energy?
There is nothing like that. energy cannot be created
Sources of gravitational energy?
Gravity is created by the mass of objects
Can energy be created and sometimes destroyed?
No. The laws of conservation of energy dictate that energy can neither be created nor destroyed. Mass and energy are equivalent, so energy can only change forms.
Is it true that the law of conversation of mass states that in any chemical or physical change energy is not created or destroyed?
No, the law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. However, the law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
Why do you need momentum with kinetic energy?
Momentum is the product of mass and velocity. Kinetic Energy is the product of mass and velocity squared. As you can see, since Kinetic Energy is derived from mass and velocity, and Momentum is derived from mass and velocity, you cannot have one without the other.
