| Force | a push or pull that one body applies to another |
| Net force | when two or more forces combine at the same time. |
| Balanced forces | equal in size and opposite in direction. |
| Unbalanced forces | unequal in size and/or not in the same direction. |
| Inertia | an object's resistance to any change in motion. |
| Mass and inertia | an object with greater mass has a greater inertia. |
| Newton's 1st law | an object moving at a constant velocitykeeps moving at that velocity unless a net force acts on it. |
| S.I for force | Newtons. |
| Equation for force | mass x acceleration. |
| Force of gravity | 9.8m/s squared |
