Positive and negative charges. Objects can be positively charged, negatively charged or neutral (no charge). A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged. When a charged object comes near to another object they will either attract or repel each other. If the charges are the same - they repel. If the charges are opposite - they attract.
