Forces
science words about forces
| Question | Answer |
|---|---|
| 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 forces acting on an object |
| Newton's first law of motion | states that if the net force acting on an object is zero,the object will remain at rest or move in a straight line with a constant speed |
| Newton's second law of motion | states that an object acted upon by a net force will accelerate in the direction of the force and that the acceleration equals the net force divided by the objects mass |
| 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 |
| Newton's third law of motion | states that forces always act in equal but opposite pairs |
