The weight suspended on the spring was taken away from the equilibrium position (by stretching the spring) and released.

The weight suspended on the spring was taken away from the equilibrium position (by stretching the spring) and released. Describe how the potential and kinetic energy of the load then change over time. How does the potential energy of the spring change?

The potential energy of the spring will decrease as the deformation of the spring decreases. The speed of the body will increase, and the kinetic energy will increase accordingly.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
