static electricity

Question 1

electrical conductor

electrical insulators

Answer 1

metal copper gold silver

glass plastic rubber

Question 2

electrostatic charges on materials

Answer 2

so electrons are negatively charged so if you add them to a material that becomes negatively charged but if you take them away form a material it becomes positively charged

Question 3

elecrostatic phenomina e.g. wall and balloon

Answer 3

if you rub a balloon on your jumper it then becomes charged and then when you go and stick it on the wall the negatively charged ballon repels all of the negative electrons on the wall so the positive and negative electrons attract so the balloon sticks to the wall

Question 4

dangers of electrostatic charge

Answer 4

you always need to earth something like a plane before you fuel it because otherwise you have a build up of electrostatic charge and if you have an negatively charged something you could causes huge problems
