After a long and a very much needed winter break, we began learning a new unit, energy. The first thing we learned in this unit was a new law, the law of conservation of charges. This law states that in an isolated system, the net charge will remain the same. This week along with a new law we also learned about the reactions of charges with each other. Everything has a charge it just depends if an object has a positive, negative, or neutral charge. Like in the picture above if charges have like charges then they repel from each other, but if they have unlike charges then they attract. Also if to objects have neutral charges then no reaction occurs.
