Question | Answer |
---|---|
Charge of Electrons | Negative |
Charge of Protons | Positive |
Charge of Neutrons | No charge |
How do motor convert energy | From Electrical to Mechanical |
How do generators convert energy | From Mechanical to Electrical |
What is transferred during conduction | Electrons |
What is the sudden flow of electrons between objects | Static Discharge |
Conduction | Objects are touching and electrons are transferred |
Induction | An electrically charged object is brought near a Neutral object, parts of the neutral become charge with Static Electricity |
Friction | Electrons are transferred when two neutral objects are rubbed together. |
Conductor | Metal Material |
Insulator | Nonmetal Material |
Things that make electromagnets stronger | More wire turns, greater voltage, adding dry cells, increasing the size of the iron core, and low temperature |
What most affects friction | The textures of the object and the surface. |
What two things affect gravitational force. | Mass and Distance (Mass=Greater Force) and (less distance between greater objects= Greater Force |
Mass vs. Weight Comparing the Earth to the Moon | Mas is the same everywhere, but objects weigh less on the Moon than on the Earth due to the weaker gravitational pull on the Moon. |
Like _________, opposites __________. | Repeal and Attract |
What is Static Electricity. | The buildup of electric charge on an object |
