Carmen sube las escaleras de su casa para tirar desde el segundo piso una bola a su mascota Kir cuando carmen gana energía potencial ?

It should actually be phrased, " Cuando gana energía potencial Carmen?"

Cuando esta sosteniendo la pelota en su mano, apunto de tirarla.

When she is holding the ball in her hand, about to throw it.

Explanation:

Energia potencial es cuando un objeto no se esta moviendo, en este caso, Carmen gana energia potencial cuando esta sosteniendo la pelota en su mano. Como la pelota no se esta moviendo, la energia potencial esta conservada adentro.

Potential energy is when an object isn't moving, in this case, Carmen gains potential energy when she is holding the ball in her hand. Because the ball isn't moving, the potential energy is stored inside.

I apologize for not using the proper Spanish alphabet, I'm doing this on my computer.
