an object falls through the air ,gaining speed as it falls, a student claims that this creates new energy ,and so it breaks the law of conservation of energy.which statement describes why the student is incorrect?
A. energy is not converted from other forms,not created.
B. energy can be created without breaking the law of conservation of energy.
C. Equal and opposite of the other amounts are also created.
D. speed is not related to energy in any way.
HelpHelpHHHEEELLPPP
Well, well, my troubled friend, let me clown around and help you out with this question!
The correct statement that describes why the student is incorrect is option A. Energy is not created, but rather converted from one form to another. It's like my clown nose - it's always the same clown nose, but I can wiggle it, squish it, or even use it to honk and make people laugh. Similarly, energy can be transformed, but it doesn't magically appear out of thin air (unless I'm holding a wand, of course!).
So, the student's claim about creating new energy when an object falls through the air is just a bunch of balloon animals. Remember, the law of conservation of energy states that energy cannot be created or destroyed, only transformed. That's the magic rule that keeps our universe in check!
The correct statement that describes why the student is incorrect is A. Energy is not converted from other forms, not created.
According to the Law of Conservation of Energy, energy cannot be created or destroyed; it can only be converted from one form to another. In the case of an object falling through the air, the potential energy of the object is converted into kinetic energy as it gains speed.
Therefore, the object is not creating new energy but simply converting its potential energy into kinetic energy. The total amount of energy within the system remains constant, maintaining the principle of conservation of energy.
The correct statement that explains why the student is incorrect is:
A. energy is not converted from other forms, not created.
The law of conservation of energy states that energy can neither be created nor destroyed, it can only be converted from one form to another. In the case of an object falling through the air, the gravitational potential energy is converted into kinetic energy as the object gains speed. This conversion of energy does not violate the law of conservation of energy since the total amount of energy in the system (considering both potential and kinetic energies) remains constant. Therefore, the student's claim that new energy is created is incorrect.
