The field around a charged object, how to draw it, why it gets weaker with distance, and how fields explain sparks and attraction.
You will be able to
- Draw the field pattern around a charged sphere
- Say how the field strength changes with distance
- Explain non-contact forces between charges using fields
- Explain sparking using the idea of a strong field
