This week we learned about Coulomb’s law
Which is represented by the equation F=k(q1q2)/r^2 .
Coulomb’s Law states that Electrical
Force between 2 charged objects is directly proportional to the product of the
quantity of charge on the objects and inversely proportional to the square of
the separation distance between 2 objects.
Basicly it means that the force
between two objects depends on the charge for each and how far apart the
objects are. This was observed through an experiment called the Torsion
Balance. Where a bar had opposite
charged on each side and was put next to
a charge the same as theirs, the bar was observed to turn in the direction of
the opposite charge.
The man who discovered this was named
Coulomb and he was a French Physicist known mostly for his work with friction
and developing Coulomb’s Law. Examples
of this law can be found everyday, they are things like getting shocked after
jumping on a trampoline or when you rub a balloon on your head and your hair
sticks to is and forms static.
