Question

Explain how in an electrical system like wires going from a plant to a house, there is less electrical energy at the end of the chain (the outlet in the house) compared to at the plant. How does this connect to, contradict or explain the law of conservation of energy which states that energy cannot be created nor destroyed. The answer should be 10-15 sentences long.

Answer 1

According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another. KE + PE = constant. A simple example involves a stationary car at the top of a hill.

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. The only way to use energy is to transform energy from one form to another.

Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. ... For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
