SUMMARY
Mechanical energy is not always conserved in real-world scenarios due to non-conservative forces such as friction and air resistance. However, the law of conservation of energy remains intact as energy is transformed into other forms, such as thermal energy. An example illustrating this concept is a pendulum, where mechanical energy is converted to kinetic and potential energy, but energy losses occur due to air resistance. Understanding these principles is crucial for analyzing mechanical systems.
PREREQUISITES- Understanding of mechanical energy concepts
- Familiarity with non-conservative forces
