concave lens | a lens that is thicker at the edges than it is at the middle |
convex lens | a lens that is thicker at the center than it is at the edges |
kinetic energy | the energy of motion or moving |
potential energy | the energy an object has because of its condition or position; stored energy |
motion | the action of moving or changing places or positions |
force | a push or pull upon an object resulting from the object's interaction with another object |
friction | the force that happens when two things rub together |
weight | a measurement of how heavy something is; a measure of a pull of gravity on an object |

Newton's 1st Law - Law of Inertia | An object moving in a straight line will continue moving in a straight line, unless acted on by an outside force. Also an object at rest will remain at rest, unless acted upon by an outside force. |
Newton's 2nd Law | Force will cause a change in the motion of an object. The change in motion depends on the amount of force and the mass of the object. |
Newton's 3rd Law | For each action, there is an equal and opposite reaction. |
