Assumptions and safety

In the Hooke-linear spring approximation, U_s=½kx², with k in N/m and x in METERS. The simulation converts displayed centimeters into meters and assumes a body released from rest while spring compression decreases without reversing. Released potential energy becomes kinetic energy and a user-prescribed fraction transferred to other forms. The fraction is an instructional assumption, not a measured drag, friction, or damping coefficient.

2. Visual energy conservation ledger

All three bars sum to initial stored potential energy. The labels and numerical readout give exact values independent of the colors.
