What is the principle of conservation of energy? (2021)
Step 1: Understand that energy is a property that can exist in different forms, like heat, light, and motion.
Step 2: Learn that energy can change from one form to another. For example, when you eat food, your body transforms the energy in the food into energy for movement.
Step 3: Remember that energy cannot be created from nothing or completely disappear. It can only change forms.
Step 4: Think of a simple example: when you drop a ball, the potential energy (stored energy) changes to kinetic energy (energy of motion) as it falls.
Step 5: Conclude that the total amount of energy in a closed system remains constant, even though it may change forms.
