  1. 3. Forces acting on an object that cause no change in the motion of the object (i.e., the object will stay at rest or remain in motion at a constant speed) and result in a net force equal to 0 Newtons (N)
  2. 5. The distance an object moves per unit of time, such as miles per hour
  3. 6. A force that is applied on an object by a person or another object
  4. 10. The amount of matter in an object
  5. 11. A change in velocity over time
  6. 13. The change in position of an object in a given direction
  7. 14. The international unit of measure for force; the symbol is N
  8. 17. A push or pull that can change the position or motion of an object or material
  9. 18. The location of something relative to something else; such as north , east, south or west.
  10. 20. A law that states that an object at rest will remain at rest and an object in motion will remain in motion until an unbalanced force is applied.

  1. 1. A pair of forces that exists between two objects interacting with each other; the forces are equal in size and opposite in direction
  2. 2. Motion on a straight line
  3. 4. A law that states that, when two objects interact, they exert forces on each other that are equal in size and opposite in direction
  4. 7. A force that pulls objects toward each other
  5. 8. The tendency of an object to remain at rest or in uniform motion in the same straight line unless acted upon by an unbalanced force
  6. 9. The measure of length between objects or points without regard to direction
  7. 12. A law that explains the relationship between force, mass and acceleration through the formula Force = Mass x Acceleration (N)
  8. 15. The sum of all forces acting on an object
  9. 16. A force acting on an object that causes a change in the motion of the object (i.e., the object will speed up, slow down or change direction) and results in a net force that does not equal 0 Newtons (N)
  10. 19. The distance an object moves per unit of time in a specified direction.
