                                                   STATIC ELECTRICITY

1.   Static electricity is electrical charge that is at rest or not moving.

2.   The study of static electricity is called electrostatics.  

3.   There are two types of static electric charge, i.e. positive charges and negative charges.

4.   Positive charges consist of protons. Protons cannot move.

5.   Negative charges consist of electrons. Electron transfer happens when two different
      materials are rubbed together.                                    A.   Characteristics of static electric charges

1.   Positive charges and negative charges have the ability to attract or repel other charges.

2.   Charges of the same type (like charges) repel one another.

3.   Charges of different types (unlike charges) attract one another.

4.   The repulsive force and attractive force that exist between electrical charges is called
      electrostatic force.  

5.   Electrostatic force is a type of force caused by static charges.

6.   Electrostatic force on a charged object causes a neutral object to be attracted to it.
   Different charges attract                                       Same charges repel one another
              one anotherUnlike charges attract each other and like charges repel each otherB.   Production of static electric charges

1.   Static electric charges can be produced on a neutral object by rubbing it with a different
      material like a woollen or silk cloth.

2.   When two different materials are rubbed, electron transfer occurs. One of the material
      receives electrons while the other loses electrons.

3.   The material that receive electrons becomes negatively charged because it has more
      electrons than protons.

4.   The material that loses electrons becomes positively charged because it has more
      protons than electrons.

5.   An object is neutral if the number of positive charges...
