Laws of Conservation of Energy in Conversions
The Law of Conservation of Energy says that energy cannot be created nor destroyed; it only changes from one form to another.
This means a system's energy stays the same, even when transforming into different types.
Imagine a swinging pendulum. It has the most potential energy at its highest point, where its kinetic energy is zero. As it swings downward, that energy turns into kinetic energy.
In an ideal case, when it reaches its lowest point, its kinetic energy is at its highest, and its potential energy is zero, but the total energy remains the same.
Over time, friction and air resistance convert some of that energy into heat, which slows the pendulum down.
A campfire is another example. The chemical energy in wood isn't lost. It changes into heat and light when the wood burns.
When a battery powers a flashlight, the chemical energy stored in the battery gets transformed into electrical energy.
This electrical energy then changes into light and heat energy. However, the total energy remains the same.
Every action around us follows this law, proving that energy is always changing but never vanishes.
