  2. Force • A push or a pull

  3. Inclined plane • A simple machine that is a flat surface with one end higher than the other

  5. Motion • A change in the position of an object as it is moving

  6. Friction • A force that slows down a moving object when it rubs against another object

  7. Magnet • An object that pulls objects made from iron toward it

  9. Attract • To pull toward- unlike poles on a magnet attract each other

  10. Repel • To push away-like poles on a magnet repel each other

  11. Magnetic Field • All of the invisible magnetic forces around a magnet

  12. Gravity • A force that attracts objects to each other. The force of gravity holds you to Earth.

  13. Simple Machine • A machine that makes work easier • Has few or no moving parts

  14. Wedge • A simple machine made of two inclined planes joined together • Example: an ax
