Kinetic energy flashlight
WebEnergy conversions involved. Rubbing hands together to make them warm. Kinetic energy to thermal energy. Using a battery -powered flashlight. Chemical energy to electrical energy (in the battery) Electrical energy to radiant energy (in the bulb) An object speeding up as it falls. Gravitational potential energy to kinetic energy. WebThe movement of electrons (traveling electrons have kinetic energy and can-do work) was created by the voltage differential between the ends, and the opposition to this flow produced heat and light. It seems it’s the same with an AC circuit as well. Sunlight There will be a large number of helium and hydrogen atoms on the sun.
