Question

based on what you learned about the bike ride, which of the following statements about energy transformations are true? select all that apply. in all energy transformations, kinetic energy changes. an energy transformation involves two or more types of energy. chemical potential energy in muscle cells can be converted into kinetic energy.

Explanation:

1. Energy transformations can involve various forms like potential - kinetic, chemical - kinetic etc. Not all involve a change in kinetic energy, for example, in some cases potential energy can transform between different types without kinetic energy change. So the first statement is false.
2. By definition, an energy transformation occurs when one form of energy changes into another, so it involves at least two types of energy.
3. When a person rides a bike, the chemical potential energy stored in muscle cells is used to do work and is converted into kinetic energy of the bike and the rider.

Answer:

An energy transformation involves two or more types of energy.
Chemical potential energy in muscle cells can be converted into kinetic energy.
