  1. 5. a force acting on a object of system that originates outside of the object or system
  2. 7. a pulling force that acts along a connecting medium, especially a stretched flexible connector, such as a rope or cable; when a rope supports the weight of an object, the force exerted on the object by the rope is called tension
  3. 9. a push or pull on an object with a specific magnitude and direction
  4. 11. an external force that acts in the direction opposite to the direction of motion
  5. 14. a push or pull on a object with a specific magnitude and direction
  6. 15. when one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts
  7. 17. the quantity of matter in a substance

  1. 1. the net external force, ๐…net, on an object is proportional to and in the same direction as the acceleration of the object, a, and also proportional to the objectโ€™s mass, m; defined mathematically as ๐…net=๐‘š๐š or ฮฃ๐…=๐‘š๐š.
  2. 2. one or more objects of interest for which only the forces acting on them from the outside are considered, but not the forces acting between them or inside them
  3. 3. the force of gravity, W, acting on an object of mass m; defined mathematically as W = mg, where g is the magnitude and direction of the acceleration due to gravity
  4. 4. the sum of all forces acting on an object or system
  5. 6. Newtonโ€™s first law of motion: a body at rest remains at rest or, if in motion, remains in motion at a constant speed in a straight line, unless acted on by a net external force
  6. 8. the force that a surface applies to an object; acts perpendicular and away from the surface with which the object is in contact
  7. 10. the tendency of an object at rest to remain at rest, or for a moving object to remain in motion in a straight line and at a constant speed
  8. 12. a force that pushes an object forward in response to the backward ejection of mass by the object; rockets and airplanes are pushed forward by a thrust reaction force in response to ejecting gases backward
  9. 13. the study of how forces affect the motion of objects and systems
  10. 14. a situation in which the only force acting on an object is the force of gravity
  11. 16. the sum of all external forces acting on an object or system
