The usual signs and symptoms of the flu are cough, sore throat, runny or stuffy nose, body aches, headache, chills, and feeling very tired. Most people also have a fever. Others may throw-up and have diarrhea.
Electric Potential (Energy). When we harness electricity to power our circuits, gizmos, and gadgets, weâre really transforming energy. Electronic circuits must be able to store energy and transfer it to other forms like heat, light, or motion. The stored energy of a circuit is called electric potential energy.
Mechanical energy is the sum of energy in a mechanical system, or any group of objects that interact based on basic mechanical principles. This includes both kinetic energy, the energy of motion, and potential energy, the stored energy of position.eneral Background. Mechanical energy exists as both kinetic and potential energy in a system. Kinetic energy is present whenever an object is in motion. Potential energy is based on the position of an object; it is stored energy, and cannot do work on its own.
