Step 1Let's solve this problem step by step:
Step 2: Understand the Law of Conservation of Energy
The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. In a closed system, the total energy remains constant.
Final Answer
The total amount of energy remains the same. Key Insight: E_{total} = E_{potential} + E_{kinetic} + E_{heat} = \text{constant} The rubber band simply transforms its stored potential energy into other forms of energy (kinetic and heat) while maintaining the same total energy level.
