charged. The material that loses electrons is left with an equal positive charge. Describe and explain how a material can gain a negative charge in of electron movement. Describe and explain how a material can gain a positive charge in terms of electron movement. pile of shredded paper and near slow running water. how the plastic rod becomes charged and what happens to the cloth that is used to charge it. Demonstrate static electricity using a Van de Graaf generator. Pass My Exams – Static Electricity 4.2.5.1 How static can cause sparks when objects are earthed. The greater the charge on an isolated object the greater the potential difference between the object and earth. If the potential difference becomes high enough a spark may jump across the gap between the object and any earthed conductor which is bought near it. 0.5 State that when a charge on an isolated object is increased the potential difference between the object and earth is increased. What causes lightning? Why do people struck by lightning often have a burn mark at the ankle? Describe what can happen when an object that has a charge is brought near an earthed conductor. Why does a Van de Graaf generator produce a large spark but a plastic rod doesn’t? Investigate large static charges using a Van de Graaf generator. YouTube: 4.2.5.1 Electrostatic forces between objects. When two electrically charged objects are brought together they exert a force on each other. Two objects that carry the same type of charge repel. Two 1 Describe why a charged rod can attract a piece of paper that is electrically neutral. Describe the effect of two positively charged objects, two negatively charged objects and Describe an experiment to show how charged objects can attract or repel each other. Investigate the forces on charged objects placed close
