Static Charge & Electric Force Crossword Puzzle

QUESTIONS LIST:

• static : this means stationary or not moving.
• static charge : also known as static electricity, this refers to electric charges that can be collected and held in one place.
• charge : the movement, or transfer, of electrons from one atom to another changes this on the atom.
• more positive : when an atom loses electrons, the atom becomes this.
• more negative : when an atom gains electrons, the atom becomes.
• friction : this occurs when objects rub against each other, and can result in one object losing electrons and the other object gaining electrons.
• insulators : since these are materials that do not allow charges to move easily through them, they can retain a static charge.
• conductors : these are materials that allow electrons to travel freely within or through it.
• metals : these are good conductors because the atoms in them have at least one electron that is easily transferred and becomes free to move within the conductor.
• one coulomb : this is the unit of electric charge produced by takes the addition or removal of 6.25 x 10^18 electrons.
• clouds : these become negatively charged at the bottom and positively charged at the top because of the friction that occurs during a thunderstorm.
• paint : this is given an electrical charge and then sprayed onto the body of the automobile.
• grounding cable : a fuel hose contains this, which transfers any excess static charge to the ground, to prevent sparking.
• lightning rod : this is placed on top of the building so that the large amount of electric charge from a lightning strike will pass safely through it to the ground, rather than onto the building.
• force : this is defined as a push or pull.
• electric force : this is a push or pull between charged objects that can even apply force to an object without touching it.
• like : these charges repel.
• opposite : these charges attract.
• neutral : these objects are attracted to charged objects.
• directly : electric force is proportional in this way to charge.
• inversely : electric force is proportional in this way to distance.
• gravitational : this is another force that acts-at-a-distance.
• conduction : this is charging a neutral object by touching it to a charged object and transferring charge between them.
• induction : this is the process of rearranging electrons on a neutral object by brining a charged object close to it.
• photocopier : in this machine, light and powdered toner are used to produce an image using static electricity.
