You work hard to pedal your bicycle up a steep hill. you rest when you get to the top, then you let your bicycle roll quickly down the other side of the hill. you converted energy into energy, then you converted it back into energy.

Kinetic, potential and kinetic.

Explanation:

Energy helps to do any form of work. Energy can not be created and can not be destroyed. The energy are inter convertible with each other and no energy is lost during this process.

Two main types of energy are potential energy and kinetic energy. Potential energy is present in rest objects whereas kinetic energy is possessed in moving objects. On pedaling a bicycle kinetic energy is used. Dying rest this energy is converted into potential energy and further on rolling of the bicycle requires kinetic energy.

Thus, the answer is kinetic, potential and kinetic.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
