Common-Core Grade 7 - 7 Exploring energy transformations bike ride

Human cells are able to take in these molecules and use their chemical potential energy.
Increasing the distance between an object and Earth increases the gravitational potential energy stored between them.
If kinetic energy was converted into sound energy, that means kinetic energy decreased, while sound energy increased.
During an energy transformation, the total amount of energy stays the same. So, when one type of energy decreases, at least one other type of energy will increase.
The kinetic energy of an object depends on the object's speed.
An energy transformation converts one or more types of energy into other types of energy.
Muscular energy is required to ride a bike.
This is because during energy transformations, energy is converted between different types.
Muscle cells use chemical potential energy when they expand or contract to move parts of a person's body.
If chemical potential energy was converted to both kinetic energy and thermal energy, that means chemical potential energy decreased while kinetic energy and thermal energy increased. So, look for the evidence of those changes.
