Final answer:
Moving electrons possess kinetic energy due to their motion, carrying electrical energy, and potential energy when positioned within an electric field.
Step-by-step explanation:
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.
The energy in moving electrons is best described as kinetic energy, which is energy due to the motion of an object. Electrons in motion carry electrical energy, and when they are in an electric field, they have electric potential energy. The potential for these moving charges to do work is based on their positions within the electric field.
This potential energy can be converted to kinetic energy as the electrons move and accelerate. This concept is similarly observed when a brick falls from a windowsill, initially having potential energy which is turned into kinetic energy during the fall.
