Based on the law of conservation of energy which of the below is true
You can not copy and paste to this site.
The law of conservation of energy states that energy cannot be created or destroyed in an isolated system, only transferred or transformed from one form to another. Therefore, the true statement is that energy is conserved.
The law of conservation of energy states that energy cannot be created or destroyed, but it can only be converted from one form to another. Therefore, based on this law, the correct statement would be that the total amount of energy in a closed system remains constant.
To understand why this is true, you can consider the following steps:
1. Recognize the law: Start by being familiar with the law of conservation of energy, which is a fundamental principle in physics that applies to all closed systems.
2. Define a closed system: Identify the system you are considering. A closed system is a physical system that does not exchange energy with its surroundings.
3. Identify the various forms of energy: Energy can exist in various forms such as kinetic energy (energy of motion), potential energy (energy based on an object's position), thermal energy (heat energy), chemical energy, and so on.
4. Track energy transformations: Analyze the system and track the different forms of energy present. Remember that energy can change forms, but the total amount of energy remains constant.
5. Consider any external influences: Take into account any external forces or inputs that may affect the energy in the system. These inputs can cause energy to enter or leave the system, but the total energy within the closed system remains the same.
So, to summarize, based on the law of conservation of energy, the total energy within a closed system remains constant, as energy cannot be created or destroyed but only converted from one form to another.
