Electricity

The electric force between two objects is related to which pair of characteristics?

• the charge on each object and the area of contact between the two objects

• the charge on each object and the distance between them

• the charge on each object and the mas of each object

• the mass of each object and the distance between them

What is current electricity

• the build up of a charge on an object

• Energy involving a moving electric charge

• The level of power at a given moment

• Electrons flowing out of a motor

What is static electricity?

• Synonymous with magnetism

• When two conductors touch

• production of noisy electricity

• an accumulated charge on an object

Electricity can only exert a force with contact?

• True: otherwise how would the electrons flow?

• False: it's a field force, like gravity
