In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed
There are many different types of energy, which all fall into two primary forms – kinetic and potential.
Energy can transform from one type to another, but it can never be destroyed or created.

Nuclear energy is stored in the nucleus of atoms.
This energy is released when the nuclei are combined (fusion) or split apart (fission).
Nuclear power plants split the nuclei of uranium atoms to produce electricity.
What element do they use to fuel nuclear power plants?
TELOFASE
il fuso mitotico si rompe, i cromosomi iniziano a decondensarsi
ANAFASE
i cromatidi vengono tirati ai poli opposti
METAFASE
Chemical energy is stored in the bonds of atoms and molecules.
It is the energy that holds these particles together.
Stored chemical energy is found in food, natural gas, etc.
Give more examples.
i cromosomi sono allineati sul piano equatoriale, ogni cromosoma è legato da una fibra del fuso
PROMETAFASE
i cromosomi continuano a condersarsi
PROFASE
L'involucro nucleare si rompe, i cromosomi diventano visibil
G2
la cellula completa l'accrescimento e si prepara per la divisione cellulare
FASES
la cellula continua ad accrescersi e si duplicano i cromosomi
G1
La cellula si accresce
Motion energy or mechanical energy is the energy stored in objects; as objects move faster, more energy is stored.
Examples of motion energy include wind, a flowing river, etc.
Give more examples.
Energy storage is the capture of energy produced at one time for use at a later time. A device that stores energy is generally called an accumulator or battery.

The battery acquires its charged condition either by recharging or in the manufacturing of the unit.
During discharge, the chemical on the anode releases electrons, and ions in the electrolyte undergo an oxidation reaction.
Name the particular compounds in which energy is stored:
variabilità genetica
Thermal energy storage is achieved with widely differing technologies.
Depending on the specific technology, it allows excess thermal energy to be stored and used hours, days, months later, at scales ranging from the individual process, to building or town.
What are 3 types of thermal energy?
