during an energy transformation, some types of energy may not change. read the passage about the next part of the ride. think about how kinetic energy, chemical potential energy, and gravitational potential energy changed. keep in mind that increasing the distance between an object and earth increases the gravitational potential energy stored between them. eventually, ellen reached a hill. she pedaled as hard as she could to maintain a steady speed on her way up the hill. click the blue words to correct the statement. assume ellens mass did not change. as ellen rode up the hill, her kinetic energy stayed the same. at the same time, the chemical potential energy stored in her muscle cells stayed the same, and the gravitational potential energy stored between her and earth stayed the same.

Answer

Explanation:

Step1: Analyze kinetic energy

Since Ellen maintained a steady speed and mass didn't change, by the formula $K = \frac{1}{2}mv^{2}$, kinetic energy stayed the same.

Step2: Analyze chemical - potential energy

Ellen pedaled hard, so her muscle cells used chemical - potential energy. Thus, chemical potential energy decreased.

Step3: Analyze gravitational - potential energy

As she rode up the hill, the distance between her and Earth increased. By $U = mgh$, gravitational potential energy increased.

Answer:

As Ellen rode up the hill, her kinetic energy stayed the same. At the same time, the chemical potential energy stored in her muscle cells decreased, and the gravitational potential energy stored between her and Earth increased.
