SUMMARY
The discussion clarifies that work (W) is not included in the sum of forces in dynamics because it is not a force itself but rather a measure of energy transfer. The net force acting on a body is determined by the weight acting downward and the opposing forces from the springs, which together influence the body's acceleration. The relevant formula for the energy stored in a linear spring is ½.kx², which is essential for understanding the dynamics involved without needing calculus.
