1). an electric motor running Electrical energy is changing into kinetic energy and a little bit of heat
2). light a match The chemical energy stored in the match head changes into light and heat energy.
3). a light bulb Electrical energy is changed into light and heat energy.
When a cyclist rides downhill, their gravitational potential energy is converted into kinetic energy as they descend, along with some heat energy due to friction. This transformation highlights how energy can change forms during motion. Therefore, gravitational potential energy transforms into both kinetic and heat energy during this process.
