  1. 2. is a force that is the opposite of motion between two surfaces that are touching causing it to slow down. A frictionless surface will not affect motion
  2. 6. is a speed in a given direction
  3. 10. the amount of matter in an object measured in grams or kilograms
  4. 12. unit of measurement of force(N)
  5. 15. Newton's First Law that states that an object's motion will not change unless an unbalanced force acts on it
  6. 17. 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
  7. 18. support force of a surface an object is in contact with preventing it from falling
  8. 20. group of items interacting to form a unified whole
  9. 21. any push or pull between two objects, measured in Newtons(N)
  10. 22. is the tendency of all objects to resist change in motion dependent on mass, to keep doing what they are already doing
  11. 23. is the rate at which velocity changes (speed or direction) over time as a result of unbalanced forces and mass of the object
  12. 24. forces acting on an object that cancel each other out causing a net force of zero and causing no change in movement

  1. 1. three principles that explain the relationship between an object's motion and the forces applied to it;at least two laws always apply
  2. 3. is the sum of all forces acting on an object within a system, includes both magnitude (strength) and direction
  3. 4. Newtons 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
  4. 5. net force greater than zeros that cause changes in motion of an object in the direction of the greater force
  5. 7. is the speed that is steady or unchanging
  6. 8. change in an objects position or location
  7. 9. a force acting directly in contact with an object
  8. 11. is the rate of change at which an object moves a distance over time
  9. 13. is the total distance traveled divided by total amount of time taken
  10. 14. 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
  11. 16. energy of objects in motion
  12. 19. stored energy of an object due to position, condition, or composition (ex: chemical energy can be food,propane gas, or batteries)
