multiple - choice question
which of the following correctly explains the energy forms in order when considering a roller coaster?
¿cuál de las siguientes explica correctamente las formas de energía en orden al considerar una montaña rusa?
b. at the very top of the roller coaster there is stored energy in the form of kinetic energy. when the roller coaster cars go down, potential energy is being released.
b. en la parte superior de la montaña rusa hay energía almacenada en forma de energía cinética. cuando los vagones de la montaña rusa bajan, se libera energía potencial.
a. at the very top of the roller coaster there is stored energy in the form of potential energy. when the roller coaster cars go down, kinetic energy is being released.
a. en lo más alto de la montaña rusa hay energía almacenada en forma de energía potencial. cuando los vagones de la montaña rusa bajan, se libera energía cinética.

Explanation:

Potential energy is related to height and is maximum at the top of the roller - coaster. As the cars descend, this potential energy is converted into kinetic energy (energy of motion). Option A correctly describes this energy - conversion process. Option B has the wrong forms of energy assigned at the top and during descent.

Answer:

A. At the very top of the roller coaster there is stored energy in the form of potential energy. When the roller coaster cars go down, kinetic energy is being released.
