Over the course of our Electricity Unit, we have learned about electric charges and how they react when encountering each other.
Positive and Positive/Negative and Negative
Like charges repel.
Positive and Negative:
Unlike charges attract.
Neutral and Positive/Negative
Neutral objects attract charged objects.
I like how you have summarized the ideas on charge here in this post. Would love to see some pictures embedded in here. Other than that, your answers are bang on.
