Force+Newton's Laws
| Term | Definition |
|---|---|
| Balanced Forces | two or more forces whose effects cancel each other out and do not change the motion of an object |
| Center of Mass | point in a object that moves as if all of the object's mass were concentrated at that point |
| Force | a push or pull |
| Friction | force that acts to oppose sliding between two surfaces that are touching |
| Net force | combination of all forced acting on an object |
| Newton's 1st Law | An object in motion will stay in motion, an object at rest will stay at rest, unless acted on by an outside force. |
| Newton's 2nd Law | states that an object acted upon by a net force will accelerate in the direction of the force |
| Newton's 3rd Law | states that forces always act in equal but opposite pairs |
| Unbalanced Forces | two or more forces acting on an object that do not cancel,and cause the object to accelerate |
| Weight | gravitational force between an object and Earth |
