Static Electricity

Question 1

Electric charge

Answer 1

A property of matter that experiences a force when next to other charges or in a electrical field

Positive and positive repel
Negative and negative repel
But positive and negative attract

Coulomb: unit

Question 2

Electrical fields of charges

Answer 2

Regions where charges experience a force

The closer together of the lines the stronger it is

Question 3

Insulators

Answer 3

Insulators are objects that do not have free electrons therefore they cant carry charge

When u rub two insulators together Eg: a cloth and a glass rod, one of the objects will gain electrons (the glass rod) and one will lose electrons (the cloth) this is due to friction

So the glass rod is now negatively charged and the cloth is positively charged

Question 4

Charging conductors by induction

Answer 4

When a positively charged rod is brought close to a metal sphere the negatively charged atoms come closer to the rod in the sphere and the positively charged atoms try to go further away from the rod
