A mass fixed to the bottom end of a spring moves up and down. At which positions along the mass’s motion are the gravitational potential energy of the mass (GPE), the elastic potential energy in the spring (EPE) and the kinetic energy of the mass (KE) at their maximum values?
- AGPE: bottom, EPE: middle, KE: top
- BGPE: bottom, EPE: top, KE: middle
- CGPE: top, EPE: bottom, KE: middle
- DGPE: top, EPE: bottom, KE: top
