Question

Cuando se produce una transferencia energética, parte de la energía se disipa siempre en forma de luz??

Answer 1

Energy Stored

Energy cannot be created or destroyed, but it can be saved in various forms. One way to store it is in the form of chemical energy in a battery. When connected in a circuit, energy stored in the battery is released to produce electricity.If you look at a battery, it will have two ends: a positive terminal and a negative terminal. If you connect the two terminals with wire, a circuit is formed. Electrons will flow through the wire and a current of electricity is produced.

Energy can also be stored in many other ways. Batteries, gasoline, natural gas, food, water towers, a wound up alarm clock, a Thermos flask with hot water and even pooh are all stores of energy. They can be transferred into other kinds of energy. 


When you slide a snooker ball on the board (table) it moves quickly, and then slowly, and gradually comes to a stop. This means that the kinetic energy (moving) of the ball decreases and eventually to zero when the balls come to rest. 
With zero external force on the pool table, the energy of the ball must be conserved. Then, what happened to the kinetic energy? Kinetic energy has been dissipated through friction.
