Reason Why Energy Cannot Be Created Nor Destroyed
At the core of this concept lies the Law of Conservation of Energy, a fundamental principle of physics.
According to this law, the total energy of an isolated system remains constant over time.
In simpler terms, energy cannot be created out of nothing, nor can it vanish into thin air. It merely transforms from one form to another, from potential to kinetic, and vice versa.
This principle is not only a cornerstone of classical physics but also finds its place in modern theories like the law of thermodynamics.
What is Energy?
Before diving deeper into the concept, let’s establish what energy actually is. In physics, energy is the property of matter that enables it to perform work or produce an effect.
It exists in several forms, such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), electromagnetic energy (light and radiation), and more.
Each form of energy is interconnected and can be converted into another with the appropriate conditions.
The Fundamental Law of Conservation of Energy
The Law of Conservation of Energy states that the total energy of an isolated system remains constant. This means that energy cannot be created or destroyed within the system; it can only change from one form to another. In mathematical terms, the law can be expressed as follows:
Total Energy (E) = Kinetic Energy (KE) + Potential Energy (PE) + Internal Energy (IE)
This equation represents the sum of the various energy components within the system.
Regardless of the changes occurring in the system, the total energy will always remain the same.
Examples of Conservation of Energy in Everyday Life
The Law of Conservation of Energy manifests in numerous instances in our daily lives. Let’s look into some relatable examples:
Ex. 1: Ball Thrown in the Air
When you throw a ball, the potential energy of the ball at rest is converted into kinetic energy as the ball falls.
The kinetic energy is then converted into thermal energy as the ball hits the ground and bounces back up.
Throughout this process, the total energy of the system remains constant.
Ex. 2: Food Consumption
When you eat food, the chemical energy in the food is converted into thermal energy, which your body uses to stay warm and to power your muscles.
The energy from the food is not destroyed, but rather transformed and utilized by your body.
Ex. 3: Burning a Candle
When you burn a candle, the chemical energy in the wax is converted into light and heat energy.
The wax undergoes a chemical reaction with oxygen, releasing energy in the form of heat and light.
The total energy of the system is conserved during this process.
Implications for the Future
Understanding the conservation of energy has far-reaching implications for various fields, including science, engineering, and environmental sustainability.
