Maddie should ask her doctor what the terms he/she used (that she didn't understand) mean. Or she can go the sarcastic route and just say "In English please."
I would love to help answer, but i think i need a little more context here.
If the pitcher holding the ball that mean if it doesn't have any motion so it has Potential energy in that case.
But in other case if the pitcher throwing or catching the ball it means the ball have motion so it has Kinetic energy.
