Across 4. Forces on an object that cause change in the motion of the object. 5. For every action, there is an equal and opposite reaction. 7. The path that an object is moving or facing. 10. A location to which another location is compared. 11. A push or pull that changes the motion or position of an object. 13. The horizontal line that represents time. 19. Average distance covered by an object per unit time. 20. Objects in motion stay in motion, objects at rest stay at rest, unless acted upon by force. 21. The vector sum of all the forces that act upon an object. 22. Unit for force. 23. The point or area occupied by a physical object.

Down 1. A graph that represents distance traveled in increments of time. 2. Forces on an object that do not change the motion of the object. 3. The resistance that one surface or object encounters while moving over another. 6. Force = Mass x Acceleration 8. The basic SI unit for time. 9. The universal force of attraction acting between all matter. 12. Speeding up, slowing down, or changing direction. 14. A graph in which the data are represented by points connected by one or more lines. 15. The vertical line that represents distance. 16. The measurement of the rate of change of position with respect to time. 17. The basic SI unit for length. 18. A change in an object's position, direction, or location.
