Rub a balloon on your hair and it sticks to the wall and lifts your hair toward it. Nothing was added but a brisk rub, yet the balloon now pushes and pulls on things across a gap. That is electric charge at work.
There are two types of charge, positive and negative. Like charges repel and unlike charges attract. Rubbing two insulators together transfers electrons: the one that gains electrons becomes negative, the one that loses them becomes positive.
There are two kinds of electric charge, positive and negative. Like charges repel and unlike charges attract. An insulator can be charged by friction, which transfers electrons.
The object that gains electrons becomes negative; the one that loses electrons becomes positive.
Transfer electrons between objects and watch the charges attract or repel.
Four quick checks. Each correct answer earns XP and lights this skill on your star map.
Two objects carry the same sign of charge. They will...
A polythene rod rubbed with a cloth gains electrons. The rod becomes...
Charging an insulator by friction transfers...
A positive charge and a negative charge will...
Charging by friction shifts electrons from one surface to the other.
It is electrons that move, not positive charge. The object that gains electrons becomes negatively charged, and the one that loses electrons is left positive.
Unlocks once the four checks above are done. Worth more XP, written in the style of Paper 2.
Two light balls hang on threads and swing apart from each other. This shows they carry...
A cloth rubbed on a rod loses electrons to the rod. The cloth is left...
When a plastic comb is charged by rubbing, the particles that are transferred are...
Electric charge is mapped. Keep the chain going.
