Science EOC List 1
Forces and Motion
| Term | Definition |
|---|---|
| balanced forces | forces on a object that combine to give a zero net force and do not change the motion or direction of the object. |
| gravity | attractive force between two objects that depends on the masses of the objects and the distance between them. |
| direction | with reference to the point or region toward which it is directed |
| displacement | distance and direction of an object’s change in position from the starting point. |
| electrical force | the net movement of electric charges in a single direction, |
| force | a push or pull exerted on an object. |
| friction | force that opposes the sliding motion between two touching surfaces. |
| magnetic force | attraction or repulsion that arises between electrically charged particles because of their motion. |
| mass | amount of matter in an object. |
| motion | the action or process of moving or being moved. |
| acceleration | rate of change of velocity; can be calculated by dividing the change in the velocity by the time it takes the change to occur. |
| net force | sum of the forces that are acting on an object. |
| speed | distance an object travels per unit of time. |
| unbalanced force | forces on a object that combine to give a net force NOT equal to zero and changing the motion and/or direction of the object. |
| weight | gravitational force exerted on an object. |
| mass | amount of matter in an object. |
