A mass is attached to the bottom end of a vertical spring which is fixed at its top end. The mass is pulled down and released, performing vertical simple harmonic oscillations. During the motion, the spring remains stretched at all times.
Which row in the table correctly describes the energy of the spring-mass system when the mass is at its lowest point in its oscillations?
| Elastic potential energy | Gravitational potential energy | Kinetic energy | |
|---|---|---|---|
| Row A | Maximum | Minimum | Zero |
| Row B | Minimum | Maximum | Zero |
| Row C | Maximum | Minimum | Maximum |
| Row D | Minimum | Minimum | Zero |
Row A
Row B
Row C
