Energy isn't conserved and actually gets used up.

Mechanical Energy converts into potential energy and then she stops.

Mechanical Energy gets converted into thermal energy through friction.

explain your answer

Mechanical Energy gets converted into thermal energy through friction

Explanation: when the skateboard is rubbing against whatever it’s rolling on it creates friction which slows down the skateboard, the mechanical energy is then converted into thermal energy. If you’ve ever touched the bottom of a wheel after going fast it typically feels a little warm.
