| Newton's 1st Law | The law of inertia-Objects tend to stay in motion or at rest until an unbalanced force acts upon them |
| Newton's 2nd Law | This law satates that Force=MassxAcceleration. |
| Newton's 3rd Law | For every action, there is an equal and opposite reaction. |
| Black Hole | An object said to be created by the supernova explosion of a large star, it is so dense and its gravitational pull is so strong that not even light can escape it. |
