Observation/Explanation

Name:_____________ Analysis: 1. What happens to an object after rubbing it?

2. What is the charge of the objects that were NOT rubbed?

3. What determines if an object becomes negatively or positively charged?

4. If an object has the same number of ________________ and ________________ it is uncharged/neutral. 5. If an object gives away electrons it becomes ________________ charged. 6. If an object takes electrons it becomes __________________ charged.

Conclusion – The Law of Electric Charges! 1. Objects are _____________________ by friction. 2. Charges objects ___________________ (attract/repel) uncharged/neutral objects. 3. Like charges ____________________ (attract/repel) one another. 4. Unlike charges ____________________ (attract/repel) one another....
