  1. Objects tend to continue the motion they already have unless they are acted on by forces
    Newton's first law 
  2. Is a push or pull, or any action that has the ability to change motion
    Force 
  3. Property of an object that resists change in its motion
    Inertia 
  4. Metric unit of force
    Newton 
  5. Is used to describe the total of all forces acting on an object 
    Net force 
  6. The rate of change in velocity; at which your speed increases
    Acceleration 
  7. Describe the motion that is slowing down 
    Deceleration 
  8. Relates the net force on an object, the mass of the object, and the acceleration 
    Newton's second law 
  9. It is accelerating due to the force of gravity and no other forces are acting on it 
    Free fall 
  10. Objects in free fall on Earth accelerate downward at 9.8 m/sec2 
    Acceleration due to gravity 
  11. Is speed with direction; rate of motion and the direction 
    Velocity 
  12. Force of gravity on an object (mass* acc of gravity)
    Weight 
  13. Acts against the direction of the object's motion/ fluid friction opposing the motion of an object moving through it
    Air resistance
  14. The maximum speed reached by an object in free fall; the speed at which the forces of gravity and air resistance are equal 
    Terminal speed 
  15. A line is the ration of the rise over run
    Slope
