As the cart moves to the positions along the track, it has varying levels of kinetic and potential energy. However, throughout the entire ride, the SUM TOTAL of potential energy PLUS kinetic energy is always equal. Explain why this is true.

answer

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

it would be a gas formation
