QUESTION:
1.
How is the relation between the interference of time needed
to create static electricity and electric force?
2.
How is the relation between the distance of static
electricity in 2 objects and electric force?
3.
How is the relation between the quality of charge and
electric force?
OBJECTIVE: To know the relation between the
factors that influences the quality of static electricity and the relationship
with electric force
HYPOTHESIS:
1.
The longer time needed to create electric force of static
electricity will make electric force stronger
2.
The shorter distance between object and electric force of
static electricity will make electric force stronger
Then the variable to prove the
hypotheses are:
The 1st Experiment:
a.
Manipulation Variable: The interval of rubbing the plastic
ruler with hair.
b.
Respond Variable :
Ruler with the more time to rubbing will attract paper more.
c.
Control Variable :
same plastic ruler, same small cut of paper, same hair with same pressure and
velocity when rubbing, same watch.
The 2nd Experiment:
a.
Manipulation Variable: The distance between plastic ruler
and small cut of paper.
b.
Respond Variable :
Ruler with the closed distance with paper will attract paper more
c.
Control Variable :
same plastic ruler, same small cut of paper, same hair with same pressure and
velocity when rubbing, same watch.
