Science - Law of Conservation of Energy

The law of conservation of energy states that energy cannot be created or destroyed but can be transformed from one form to another or transferred from one object to another.

Explanation

In a closed system, the total amount of energy remains constant. Energy transformations occur without any net loss or gain of total energy. For example, potential energy can be converted into kinetic energy, and vice versa.

Examples

  • A falling object converts potential energy into kinetic energy.
  • A light bulb converts electrical energy into light and heat energy.
  • A plant converts light energy into chemical energy through photosynthesis.

Simple Experiment

Pendulum: Observe a pendulum swinging. At its highest point, it has maximum potential energy and minimum kinetic energy. At its lowest point, it has maximum kinetic energy and minimum potential energy. The total energy (potential + kinetic) remains constant (ignoring air resistance).

Important Note: While energy is conserved, the quality of energy may degrade over time. For instance, some energy is often converted into heat due to friction, which is less useful for doing work.
