Respuesta :
D) Potential gravitational energy. Since the roller coaster cars are a the top of the roller coaster they have potential energy due to the gravity's downwards pull on them.
D) potential gravitational energy
What is potential gravitational energy ?
Potential gravitational energy is the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field. In simple terms, it can be said that potential gravitational energy is an energy that is related to gravitational force or to gravity.
There are a many types of potential energy but when we talk about the height , when something is kept on a certain height their occur a gravitational force acting on that object and potential gravitational energy can be calculated as U = m*g*h , since roller coaster has potential energy when it is sitting at the top of this loop
hence , correct answer is D) potential gravitational energy
