| Term | Definition |
|---|---|
| Attract | To pull objects toward one another |
| Convert | To change from one type to another |
| Electromagnetic | A type of magnet in which the magnet field is produced by an electric current |
| Energy | The ability to move or change |
| Force | A push or pull that can change the motion of an object |
| Kinetic energy | The energy that an object has because it is moving |
| Magnetic field | The space around a magnet in which magnetic forces can act on object objects |
| Magnetic field line | A line that connects opposite magnetic poles and represents the strength and direction of the magnetic field |
| Magnetic pole | One of the two opposite ends of a magnet |
| Model | An object, diagram, or computer program that helps us understand something by making it simpler or easier to see |
| Potential energy | The energy that is stored in an object or system |
| Refute | To provide evidence that goes against a claim |
| Repel | To push objects away from each other |
| Magnetized | An attractive and repulsive phenomenon produced by a moving electric charge |
| Gravity | The force of fundamental attraction between all things that have mass or energy |
| Gravitational potential energy (GPE) | Energy stored in an object due to its position above earth surface |
| Electrostatic forces | An attractive and repulsive force between particles are caused due to their electric charges |
| Ion | Charged particle negative or positive |
| Non-contact forces | A force which acts on an object without coming physically in contact with it |
| Magnitude (strength) | Increases if all the forces are acting in the same direction, and decreases if the forces are acting in different directions |
| Isolate | To separate or set apart |
| Transfer | To move from one object to another or one place to another |
| Variable | Something that can be changed and may be measured |
| Polar change (north/south) | A molecule has unevenly distributed electrical charges, where one side of the molecule has a slightly positive charge, and the other side has a slightly negative charge, essentially creating distinct “poles” of charge on the molecule. |
| Neutral change | An object has an equal number of positive and negative charges, resulting in a total charge of zero |
| Current (negative/positive) | A flow of electrical charge |
| Electrostatic (Static electricity) | A buildup of electric charge on an object, usually created by rubbing two materials together, causing a transfer of electrons and leaving one object with a positive charge and the other with a negative charge |
| System | A set of interacting parts forming a complex hole |
