ELECTROSTATICS REVIEW QUESTIONS The gravitational force is ________________than the electrical force. If an object gains electrons it has a ____charge. The only atomic particle that can move from one object to another is the ___________ and it has a ____________charge. If an atom has equal numbers of protons and electrons it is said to be _____________. The unit for charge is the ______________. The relationship between force and the distance between charges is _________________. Hint: When the distance decreases, the force A _________________ is a device used for determining the charge on an object. Once a charge that has gained electric potential energy is released, the potential energy is converted to ______________ energy. Electric potential is measured in _________. An atom that has gained or lost an electron is called a ________________. _____________occurs when the charges within a neutral object are separated causing one side of the object to be positive and one side to be negative. The space around an electric charge is called an ____________. Electric field lines point _______ from a positive charge. Materials that allow charge to move freely are called __________________. Two examples of conductors include: Touching the ground to eliminate excess charge is called ________. Charging a neutral object by touching it with a charged object is called charging by ________. The study of electric charges is called ____________. Like charges __________ and unlike charges __________________. If an object has a positive charge is has _______electrons than protons. When an object is charged by friction, _________ are _________from one object to another. Materials in which charge does not move easily are called _____________________. Two examples of insulators are: Electric potential energy is measured in _______. The electric field is a _________quantity because it has ________ and direction. Electric field strength is measured in _____. An electric charge gains energy when _______is done on the charge. Hint: This is done when the charge is moved against the electric field.
