ELECTROSTATIC SERIES WORKSHEET   Using the Electrostatic Series  chart complete the information below.                     1. When charging objects by friction c harged objects are rubbed together and electrons are Transferred from one object to another.  2. The objects HIGHER on the list have a stronger hold on electrons. When these objects

__lose____  their electrons, they become __positivly___________ CHARGED.  3. The objects LOWER on the list have a _  stronger________ hold on electrons and a lways

___gain____ electrons from objects higher on the list. When these objects  gain electrons, they become _  ___negativly___________ CHARGED.   lastic rod, the cat’s fur  becomes __positive_________ in 4. When a cat's fur is rubbed onto a p charge and the plastic  rod is _  __negative__________ in charge.  5. When rubber i s rubbed with onto an  ebonite r od, the  rubber  becomes __negative________________ and the ebonite  rod is __positive____________ in charge

Charging by Contact 1. Static charges can be transferred from one object to another when they _build up static electricity________.  2. When a charged object touches a neutral object, the neutral object will have the __electrons_____ charge as the object that came in contact with it. 

Charging by Induction 1. When a charged object is brought near a neutral conductor, the charged object will push _electrons_______ in the neutral conductor around. This will make one part of the neutral object ___positive______ and the opposite end ___negative_____. The two objects do not _transfer_____ in this type of charging.   2. What would happen to the metal bar if the positive rod was brought close while the metal bar is grounded (electrically connected to the earth)?

  If one is positive and one is negative they will attract each other because they will have opposite charges making them attract to each other and when they touch they transfer a negative charge will be attracted to the positive, which means they will be charged by induction  
