Answer: The potential energy of the roller coaster increases while climbing up a hill.
Explanation:
Potential energy of the body is defined as the energy of the body due to its position .It is calculated by the formula:
P.E = mgh
Potential energy increase with increase in mass of the body and also increases with increase in the height of the body or the distance between the body and earth surfaces .
So, when the roller coaster climb up the hill the distance between the earth surface and roller coaster increases due to which potential energy also increases.
