Renovable and non-renovable energy
This form of energy is stored in matter and it can be changed into other types of energy.
POTENTIAL ENERGY
This energy comes from motion and it depends on both mass and speed.
Kinetic energy
Mechanical energy
This form of energy is the sum of potencial and kinetic energy that is used to do work.
Electrical energy
This energy comes from the movement of electrons from one to another:- lightning-static electricity-electrical cables
Chemical energy
This is released during chemical reactions, such as when fuel burns.
Sound energy
This form of energy is produced from vibrations that we can detect with our ears and bodies.
Heat energy
Heat is thermal energy that flows from warmer objects to cooler objects.
Light energy
It is natural or artificial energy that we can see with our eyes.
Renovable energy
Is made from resources that nature will replace like:- solar energy- wind energy- biomass energy- geothermal energyI's called "clean energy".
Non renovable energy
It's an energy form that can't be replace when we used it.- coal- natural gas- oil- nuclear energy
