Understanding Energy Conservation in a Spring System

The video tutorial explains a spring system with a 10-gram mass and a spring constant of 4 N/m. The mass is compressed by 10 cm and released, reaching a maximum height. The tutorial uses the principle of energy conservation to calculate this height, considering potential and kinetic energies. Simplifications are made by assuming a vacuum and zero initial velocity. The final calculation shows the maximum height is approximately 0.2 meters.
