SUMMARY
The discussion clarifies the distinction in calculating displacement for conservation of energy in different scenarios: an incline versus a projectile. When analyzing energy on an incline, the displacement is measured along the incline's path. In contrast, for a projectile, only the vertical (y-direction) displacement is relevant for work done, as the forces acting are primarily vertical. This highlights the importance of understanding the direction of forces and their impact on energy calculations.
