Describe the energy transfers and transformations that occur when a person rides a bicycle. Make sure to identify each example as an energy transfer or an energy transformation.

Explanation:

When you are pedaling the bike, it is transforming chemical energy, supplied by the breakdown of the food you eat (any food), into mechanical energy to turn the pedals (energy we produce). The chemical energy is potential and the mechanical energy is kinetic.

Hope this helps :)
