Forces Vocab

3. The force that acts to resist the relative motion of objects or materials that are in contact.
6. A diagram showing all the forces acting on an object.
9. For an object resting on a horizontal surface, the upward force that balances the weight of the object; Support Force
12. The vector sum of two or more component vectors.
15. That which exists in the space surrounding a mass, electric charge, or magnet, so that another mass, electric charge, or magnet introduced to this region will experience a force.
16. The combination of all the forces that act on an object.

1. Point at the center of an object's mass distribution, where all it's mass can be considered to be concentrated. For everyday conditions, it is the same as the center of gravity.
2. In general, a state of balance.
4. An arrow whose length represents the magnitude of a quantity and whose direction represents the direction of the quantity.
5. Any influence that tends to accelerate an object; a push or pull; measured in newtons. A vector quantity.
7. The rate at which velocity is changing. The change may be in magnitude, direction, or both.
8. The reluctance of any body to change it's state of motion. Mass is the measure of inertia.
10. A measure of an objects inertia; also a measure of the amount of matter in an object. Depends only on the amount of and wind of particles that compose an object - not on its location (as weight does).
11. The force on a body due to the gravitational attraction of another body.
13. How fast something is moving; the path distance moved per time. The magnitude of the velocity vectors.
14. SI unit of force. One newton (N) is the force applied to a one-kilogram mass that will produce an acceleration of one meter per second per second.
