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
Nuclear energy originates from the splitting of uranium atoms – a process called fission.
This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
Write down the advantages and disadvantages of Nuclear Energy.

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.
Gravitational energy is a form of potential energy.
It is energy associated with gravity or gravitational force, in other words, the energy held by an object when it is in a high position compared to a lower position.
Give 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:
