What is the meaning of energy?
In physical science, energy means the ability to do work. Work means a change in position, speed, state, or form of matter. Therefore, energy is the capacity to change matter. Everything we do involves energy

Where does chemical energy come from and how is it formed?
Chemical energy is stored in the chemical bonds of atoms and molecules. It can only be seen when it is released in a chemical reaction. When chemical energy is released, the substance from which the energy came is often changed into an entirely diffe

What is chemical energy stored in?
The energy that results during a chemical reaction is called chemical energy. It is a type of potential energy. Chemical energy is stored within the bonds of the atoms and molecules that make up a substance. Once chemical energy is released from a su

Gravitational Force
gravity states that the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them
4 of 5
Electrical Force
The strength of an electric field at a given point in space near an electrically charged object is proportional to the amount of charge on the object, and inversely proportional to the distance between the point and the object
