Problem
A 4kg block is placed on a shelf 1.2m above a table top. The table top is originally taken as the zero level of potential energy.
Explain, in one or two sentences, what numerical value the block’s gravitational potential energy will have if the shelf itself is later chosen as the zero level, and give the reason for this change.
