  1. 2. The downward force exerted on an object due to gravity. Unlike mass (which stays the same), this depends on the gravitational field strength acting on the object.
  2. 6. A simple machine that pivots around a fixed point (a fulcrum). It is used to magnify a force, making it easier to lift heavy loads.
  3. 8. The energy stored in an object due to its position or height above the ground within a gravitational field. The higher or heavier the object, the more of this energy it holds.
  4. 10. The permanent deformation of a material. When a material behaves this way, it does not return to its original shape after the force is removed.
Down
  1. 1. The specific point beyond which a material no longer obeys Hooke's Law. Past this point, the extension is no longer directly proportional to the force applied.
  2. 3. A principle stating that the extension of an elastic object (like a spring) is directly _____________ to the force applied to it, provided it hasn't passed its limit of proportionality.
  3. 4. The turning effect of a force around a specific pivot point (or fulcrum). It is calculated by multiplying the force applied by the perpendicular distance from the pivot.
  4. 5. A relationship where two quantities increase or decrease at the same rate. If you double one, the other doubles too.
  5. 7. A toothed wheel that meshes with another toothed wheel to change the speed, direction, or torque of a rotating force.
  6. 9. The ability of a material to deform under stress but completely return to its original shape and size once the load or force is removed.
