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
Hydrogen fuel is a zero-emission fuel burned with oxygen.
It can be used in fuel cells or internal combustion engines.
Name the advantages and disadvantages of Hydrogen fuel.
And protects it from predators
But fast on water
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.
Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy.
Give examples of heat energy.
But cannot have coneversations
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:
Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.
Write down the main components of a typical flywheel.
