[填空题]
If mass is a form of energy, does this mean that a so5-v fog4s:tn/ ewpc 2 rmk1/o ri o/pbhrl+ *a624vqjpring has more mass when compresse * k 4+/hr2ibvqo/oralr1j6 mpd than when relaxed?
参考答案: yes
本题详细解析:
Yes.One way to describe the energy stored in the
compressed spring is to say it is a mass increase (although it would be so
small that it could not be measured).This mass will convert back to energy when the spring is uncompressed.
