Conservation of Energy Part 5: Mechanical Energy and Conservative and non Conservative forces

The video tutorial revisits previous concepts and introduces new ones, such as work done by conservative and non-conservative forces, and mechanical energy. It explains the relationship between work and kinetic energy, and how work done by gravity and springs are examples of conservative forces. Non-conservative forces like friction are also discussed. The video ties these concepts together by showing how total work is the sum of work done by both conservative and non-conservative forces. It concludes with the principle of mechanical energy conservation, emphasizing that mechanical energy remains constant if non-conservative forces do no work.
