Explore static electricity — how objects become charged, and how like and unlike charges interact.
Objects become charged by friction, transferring electrons between them, leaving one positively and one negatively charged.
Why does a comb attract small pieces of paper after being rubbed on dry hair?
Rubbing transfers electrons, charging the comb, which then attracts the paper through electrostatic force
What happens to an object that loses electrons?
It becomes positively charged
Like charges (both positive or both negative) repel each other. Unlike charges (one positive, one negative) attract each other.
What happens when two positively charged objects are brought close together?
They repel each other
What happens when a positively charged object and a negatively charged object are brought close together?
They attract each other
1. How does an object typically become charged?
2. What happens when an object gains electrons?
3. Do like charges attract or repel?
4. Do unlike charges attract or repel?
5. Why does a charged balloon stick to a wall?
Great work finishing every chapter. Onwards to new challenges!
