Electric charge & Static Electricity

Atoms contain charged particles called:

• Protons, neutrons and electrons
• Protons and electrons
• Protons and neutrons
• Electrons and neutrons 

Charges that are different ________ each other

• Repel
• Attract

In static electricity, charges

• Flow continuously 
• Flow intermittently 
• Build up in an atom
• Build up on an object

A region around charged objects where the object´s electric force is exerted on other charged objects is an electric: 

• Field
• Outlet
• Socket
• Power plant

The transfer of charge when electrons move from a charged object to another object by direct contact is called ________________

• Polarization 
• Induction 
• Conduction
• Friction 

The person whose finger is shown has walked across a carpet and is about to touch the doorknob.
Are the charges in the doorknob attracted or repelled by the charges in the finger. 

• The are attracted leaving one end of the doorknob with a negative charge
• The are repelled leaving one end of the doorknob with a positive charge
