Across 1. A long-range force due to gravitational attraction between 2 objects, generally earth and an object 4. the maxium distance the object moves from the equilibrium 11. second horizontal force on an object, opposite in direction to its force and equal in size 13. the pull exerted by a string, rope, or cable when attached to a body and pulled taut 14. acts on an object by touching it 15. a = ( F net / M) 17. constant velocity that is reached when the drag force equals the force of gravity 18. tendency of an object to resist change 19. A restoring force, that is, the push or pull a spring exerts on an object 20. the contact force that acts to oppose sliding motion between surfaces 21. the contact force exerted by a surface on an object

Down 1. means that there are no contact forces pushing up against an object. means that an objects apparent weight is 0 2. If the force that restores the onject to its equilbrium position 3. the vector sum of 2 or more forces on an object 5. the time period needed to repeat one complete cycle of motion 6. A general term used for the forces that move objects such as rockets, planes, cars and people 7. when small forces are applied at regular intervals to a vibrating or oscillating object,and the amplitude of the vibration increases. 8. attractive force that exist between all objects 9. force exerted withought contact 10. the force exerted by the scale 12. object at rest remains in rest or an object in motion continues moving in a straight line with constant speed if the net force acting on that object is 0 16. when object is at rest or is moving at a constant velocity 22. specific, identifiable, immediate cause that each force has
