Across
- 3. The vector sum of all the forces that act upon an object.
- 4. A surface of which one end or side is at a higher level than another; a rising or falling surface.
- 5. A strained state or condition resulting from forces acting in opposition to each other.
- 7. A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
- 9. Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced.
- 12. The frictional force resists force that is applied to an object.
- 14. The SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes.
- 16. A place where someone or something is put.
- 20. The speed of an object at a particular moment (instant) in time.
- 21. The property of occupying space; spatial magnitude.
- 22. The resistance that one surface or object encounters when moving over another.
- 23. An influence tending to change the motion of a body or produce motion or stress in a stationary body. The magnitude of such an influence is often calculated by multiplying the mass of the body by its acceleration.
- 25. Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
- 27. A unit of weight in general use equal to 16 oz. avoirdupois (0.4536 kg).
- 29. Forces applied to an object in opposite directions that are not equal in size.
- 30. Newton's first law of motion states that there must be a cause.
Down
- 1. The acceleration of a body in free fall under the influence of earth's gravity expressed as the rate of increase of velocity per unit of time and assigned the standard value of 980.665 centimeters per second
- 2. The speed of something in a given direction.
- 6. The rate at which someone or something is able to move or operate.
- 8. A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
- 10. When the speed of an object remains the same.
- 11. The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
- 13. The reduction in volume (causing an increase in pressure) of the fuel mixture in an internal combustion engine before ignition.
- 15. The quantity called momentum that characterizes motion never changes in an isolated collection of objects
- 17. The quantity of motion of a moving body, measured as a product of its mass and velocity.
- 18. A state in which opposing forces or influences are balanced.
- 19. If two individual forces are of equal magnitude and opposite direction.
- 24. Downward movement under the force of gravity only.
- 26. Increase in the rate or speed of something.
- 28. The friction between two bodies that are in sliding contact.
