  1. 6. Newton's Third law states that all forces occur in contact pairs where every action force has a reaction force that is equal in strength and opposite in direction.
  2. 11. Newton's second law of motion states that the acceleration of an object depends on its mass and the amount of force applied where F=ma, objects accelerate in the direction of the unbalanced force. Acceleration is proportional to force but inverse to mass.
  3. 12. forces acting on an object that cancel each other out causing a net force of zero and causing no ching in movement
  4. 13. is a force that is opposite of motion between two surfaces that are touching causing it to slow down. A frictionless surface will not affect motion.
  5. 15. is speed that is steady or unchanging.
  6. 17. gravity is the pull toward another object based on its mass. Gravity is constant meaning it is always pulling objects down at 9.8m/s2
  7. 21. three principles that explain the relationship between an object's motion and the porces applied to it;at least two laws always apply
  8. 22. energy of objects in motion
  9. 24. is the summer of all forces acting on an object within a system, includes both magnitude(stength) and direction

  1. 1. change in object's position or location
  2. 2. unit of measurement of force(N)
  3. 3. net force greater than zero that cause changes in motion of an object in the direction of the greater force
  4. 4. any push or pull between two objects, measured in Newtons (N)
  5. 5. is the rate at which velocity changes (speed or direction) over time as a result of unbalanced forces and mass of the object.
  6. 7. Newton's first law states that an object's motion will not change unless an unbalanced force acts on it. Meaning if an object is moving it stays moving at the same speed and direction, until forced to changed.
  7. 8. is the rate of change at which am object moves a distance over time.
  8. 9. stored energy of an object due to position, condition, or composistion
  9. 10. is speed in a given direction
  10. 14. force a force acting directly in contact with an object
  11. 16. is the total distance traveled divided by total amount of time taken.
  12. 18. group of items interacting to form a unified whole
  13. 19. is the amount of matter in an object measured by grams or kilograms.
  14. 20. support force of a surface an object is in contact with preventing it from falling
  15. 23. is the tendency of all objects to resist change in motion dependent on mass, to keep doing what they are already doing
