12 terms
Terms | Definitions |
|---|---|
 Equilibrium | In general, a state of balance. Example: The state of a body on which no net force acts. |
| Force | Any influence that tends to accelerate an object; a push or pull; measured in newtons. A vector quantity. |
| Friction | The force that acts to resist the relative motion (or attempted motion) of objects or materails that are in contact. |
| Inertia | The reluctance of any body to change its state of motion. Mass is the measure of inertia. |
| Kilogram | The fundamental SI unit of mass. One kilogram (symbol kg) is the amount of mass in one liter of water at 4 degrees celcius. |
| Law Of Inertia | Everybody continues in its state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by a net force exerted upon it. Also known as Newton's first law. |
| Mass | A measure of an object's interia; also a measure of the amount of matter in an object. Depends only on the amound of and kind of particles that compose an object - not on its location (as weight does). |
| Net Force | The combination of all the forces that act on an object. |
| Newton | SI unit of force. One newton (N) is the force applied to a one0kilogram mass that will produce an acceration of one meter per second per second. |
| Normal Force | For an object resting on a horizontal surface, the upward force that balances the weight of the object; also called the support force. |
| Support Force | Force that completely balances the weight of an object at rest. |
