1) What does insulator mean? a) A material that does not allow current to flow through it easily, eg wood or glass b) When charges move or separate in a neutral object, leaving areas of net positive or negative charge 2) What does polarisation mean? a) A material that does not allow current to flow through it easily, eg wood or glass b) When charges move or separate in a neutral object, leaving areas of net positive or negative charge c) A build-up of electrical charge on an object, which can be either positive or negative. d) A force between two electrically charged objects. These forces can be attractive or repulsive. 3) What is a definition of static electricity? a) A material that does not allow current to flow through it easily, eg wood or glass b) When charges move or separate in a neutral object, leaving areas of net positive or negative charge c) A build-up of electrical charge on an object, which can be either positive or negative. d) A force between two electrically charged objects. These forces can be attractive or repulsive. 4) What does Electrostatic forces mean? a) A material that does not allow current to flow through it easily, eg wood or glass b) When charges move or separate in a neutral object, leaving areas of net positive or negative charge c) A build-up of electrical charge on an object, which can be either positive or negative. d) A force between two electrically charged objects. These forces can be attractive or repulsive. 5) What is static electricity? a) build-up of electrical charge on an object. b) Some of the electrons are transferred across. This leaves an excess of negative charge on one of the objects, and a deficit on the other. 6) What happens when you rub one neutral , electrically insulating object against another? a) build-up of electrical charge on an object. b) Some of the electrons are transferred across. This leaves an excess of negative charge on one of the objects, and a deficit on the other. 7) What type of material allows electrical current to flow through it easily? a) conductor b) insulator c) Non metal d) Plastic  8) Which type of material does not allow electrical current to flow through it easily? a) Conductors b) insulators  c) Inductors d) Metal 9) Which materials can be charged by friction? a) Conductors b) Inductors c) Insulators d) Metals 10) What is the term for an object which contains equal numbers of positive and negative charges? a) positive b) negative c) insulator d) neutral 11) What type of charge does an electron have? a) positive b) neutral c) negative d) uncharged 12) What happens when objects with the same static charge are near to each other? a) they repel b) They attract c) they do not affect eachother d) They levitate 13) What happens when objects with the opposite static charge are near to each other? a) They repel b) they do not affect eachother c) They attract d) They levitate 14) Which type of charge can be easily transferred between insulators? a) positive b) negative c) neutral d) negative and positive 15) What might cause a neutral object to be attracted to a charged object? a) insulation b) Conduction c) Polarisation d) Gravity  16) When an atom loses an electron, which type of charge will the remaining ion have? a) positive b) Negative c) Neutral d) uncharged
