What type of charge can move?

That is because an electric charge cannot move easily through air. However, a charge can move easily through the metal of a doorknob. A material that allows an electric charge to pass through it easily is called a Metals such as iron, steel, copper, and aluminum are good conductors.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
