running: chemical > gravitational potential > kinetic/chemical firstly, chemical energy is transformed in the form of food that the body consumes. Then, as the runner lines up on the track, gravitational potential energy is used to prepare the runner to start. Lastly, once the runner begins to run, kinetic energy is being used, as well as chemical
tying hair:kinetic > elastic potential > kinetic tying your hair requires firstly kinetic energy, as the hair band is pulled into position, which is then transferred to elastic potential, as the hair band waits to be released again, and then kinetic once again, as it is released
car: chemical > thermal > kinetic a car uses chemical energy to start, which then turns to thermal energy as the ignition fires up, and as the car moves, the energy used would be kinetic
writing: chemical > kinetic writing starts off with the human body receiving food as chemical energy in order to function. It then involves the movement of the pencil, as it writes.
