What is electrical energy?
Electrical energy is the power an atom's charged particles have to cause an action or move an object. The movement of electrons from one atom to another is what results in electrical energy.
Ex:Every time you plug a toaster or cellphone charger into a wall outlet, electrical energy is powering those devices.

What is potential energy?
Potential energy is type of stored energy that an object or system of objects may have based on their size, shape, position, or even material they are made from.
A rock sitting on the edge of a cliff. If the rock falls, the potential energy will be converted to kinetic energy, as the rock will be moving.

What is chemical energy?
Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat.Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds.
Ex:batteries, natural gas and coal

What is the formula for work?
w = d x f

How does thermal energy work?
Thermal energy is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.
200
How does electrical energy work?
Electrical energy is caused by moving electric charges called electrons. The faster the charges move, the more electrical energy they carry.
Ex:Lightning, batteries
200
How does potential energy work?
Potential energy is when an object stores energy as a result of its position, making it capable of doing more work.
Ex: A rock sitting on the edge of a cliff.

How does chemical energy work?
When there's a chemical reaction between the molecules of chemical compounds, a new substance may form, and energy may be released.
Ex:Batteries, coal, gas
