A 1 kg object is initially 20m above the ground and rises to a height of 40m. Liz and Connor each measure its position, but each of them uses a different coordinate system. Select the choice that best represent the Δ P E as measured by the two scientists. Where we define Δ P E = P E f i n a l − P E i n i t i a l . Assume g = 10 m / s 2 .
