The body and spring are placed on a horizontal frictionless surface and rotated about the held end of the spring at 2.0 rev/s. There are no springs or other conservative forces beyond gravity present, so the only potential energy term at both locations is gravitational potential energy. This makes physical sensestopping force takes energy out of the system and so Some problems contain multiple force vectors acting in different directions on an object.
