Charging by rubbing
What does charging by rubbing mean?
Charging by rubbing means making an object charged by rubbing it with another object.
Does charging by induction require touching?
No
What does charging by conduction mean?
Charging by conduction means charging an object by touching it with a charged object.
What is static electricity?
Static electricity is electricity that stays in one place.
Name one pair of objects that can be charged by rubbing.
A balloon and hair.
What must be brought near an object to charge it by induction?
charged object
Do objects need to touch for conduction to happen?
yes
What is electric force?
Electric force is the push or pull between charged objects.
What happens to electrons when you rub a balloon on hair?
Electrons move from the hair to the balloon.
What happens to the charges inside an object during induction?
The charges move and rearrange inside the object.
What happens to electrons when a charged object touches a neutral object?
Electrons move from the charged object to the neutral object.
What type of force acts between two charged objects?
Electric force.
Which object becomes negatively charged when a balloon is rubbed on hair?
The balloon becomes negatively charged.
Why are small pieces of paper attracted to a charged balloon without touching it?
The charges in the paper rearrange, causing attraction.
After conduction, are both objects charged or only one?
Both objects become charged
State the rule for attraction and repulsion of electric charges.
Like charges repel and unlike charges attract.
Explain why both objects become charged after rubbing, not just one.
Electrons move from one object to the other, so one becomes negative and the other becomes positive.
Explain how an object can become charged by induction without gaining or losing electrons directly.
The electrons only move inside the object due to the nearby charged object, causing one side to become charged.
Explain why conduction usually works better with metal objects than plastic ones.
Metals allow electrons to move easily, but plastics do not.
Explain how static electricity can cause an object to attract another object without touching it.
The charges in the object rearrange, creating attraction due to electric force.
