Question

read the same passage and think about what energy transformation took place. eventually, ellen reached a hill. she pedaled as hard as she could to maintain a steady speed on her way up the hill. complete the sentence. as ellen rode up the hill, ____________ was converted into ____________. chemical potential energy . . . gravitational potential energy gravitational potential energy . . . chemical potential energy

Explanation:

When Ellen pedals up the hill, the energy stored in her body as chemical potential energy (from the food she ate) is used to do work against gravity. As her height increases while going up the hill, this chemical - potential energy is converted into gravitational potential energy.

Answer:

chemical potential energy... gravitational potential energy
