Across
- 3. a tendency to do nothing or to remain unchanged.
- 6. field a region of space around an object where a force can be exerted on another object without physical contact
- 7. the rate at which an object covers distance, defined as the total distance traveled divided by the time it took
- 10. diagram a simplified visual representation of an object that shows all the external forces, moments, and reactions acting upon it
- 11. a quantity that has both magnitude (a numerical value with units) and direction
- 12. a force, velocity, or other vector quantity which is equivalent to the combined effect of two or more component vectors acting at the same point.
Down
- 1. an interaction that causes an object to change its motion, either by altering its speed or direction
- 2. a fundamental property of an object that measures its inertia, or resistance to acceleration when a force is applied
- 4. force the support force exerted by a surface on an object in contact with it, acting perpendicular (or "normal") to the surface
- 5. force the overall force acting on an object when all individual forces are combined
- 6. a force that opposes the relative motion or attempted motion between surfaces, fluid layers, or materials in contact
- 8. of mass the point where an object's entire mass is considered to be concentrated
- 9. a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
- 13. the force required to accelerate a one-kilogram mass at a rate of one meter per second squared
