Energy Energy is the ability to do work
Energy comes in different forms:
- Heat (thermal)
- Light (radiant)
- Motion (kinetic)
- Electrical
- Chemical
- Nuclear energy
- Gravitational
People use energy for everything from walking to sending astronauts into space.
There are two types of energy:
- Stored (potential) energy
- Working (kinetic) energy
charge
In physics, charge, also known as electric charge, electrical charge, or electrostatic charge and symbolized q, is a characteristic of a unit of
matter that expresses the extent to which it has more or fewer electrons than protons. In
atoms, the electron carries a negative elementary or unit charge; the proton carries a positive charge. The two types of charge are equal and opposite.
Relationship between charge and energy
he potential
energy is a form of
energy and the potential (and therefore voltage, when differences are taken) is defined as the potential
energy (or potential
energy difference) per unit
charge, V = E / Q . That's equivalent to your equation.
