Across
- 3. The force that acts to resist the relative motion (or attempted 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; also called the 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.
Down
- 1. Point at the center of an object's mass distribution, where all its 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 . Examples: The state of a body on which no net force acts.
- 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 its state of motion. Mass is the measure of inertia.
- 10. A measure of an object's inertia; also a measure of the amount of matter in an object. Depends only on the amount of and kind of particles that com- pose an object
- 11. The force on a body due to the gravitational attraction of another body (commonly Earth).
- 13. How fast something is moving; the path distance moved per time. The magnitude of the velocity vector.
- 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
