$Potential \: \: Energy =(mass) \times (gravity \: acceleration) \times (height) \\$

_________________________________

If gravity acceleration is 10 :

$PE = 25 \times 10 \times 10$

$PE = 2500$

_________________________________

If gravity acceleration is 9.8 :

$PE = 25 \times 9.8 \times 10$

$PE = 25 \times 98$

$PE = 2450$
