This past week in class we discussed charges more deeply and how they work. We were also introduced to a few new equations that are especially vital in understanding this unit. The equation on the left can be used to calculate the force of the charges repulsion or attraction. The basic knowledge needed to be mastered for this unit is basically how like charges repel and different charges attract. We also used an electroscope to further understand charges and how they work. For instance a good example of what we learned based on an electroscope would be based on something we learned in class. So if a negative rod was placed on a neutral electroscope that electroscope would become negative also because only electrons can flow. Meaning that only electrons can move from one thing to another. The mani idea to remember with charges and charged objects they just want to be equal with each other so therefore they will lose electrons just to become equal with another and vice versa.
