Across
  1. 2. The friction force that acts on objects that are not moving
  2. 5. The continuous change in the movement of an object
  3. 7. A _ can cause a resting object to move, accelerate, or both
  4. 8. Newton's law that says the acceleration of an object is equal to the net force acting on it divided by the objects mass
  5. 9. Change in velocity divided by the total time
  6. 11. The product of an object's mass and its velocity
  7. 13. Newton's law that says the state of motion of an object does not change as long as the net force acting on the object is zero
  8. 14. The constant velocity of a falling object when the force of air Resistance equals the force of gravity
  9. 17. When an _ force acts on an object, the object accelerates
  10. 19. mass of an object multiplied by the velocity of the object
  11. 21. The friction force that opposes the direction of motion an object as it moves over a surface
Down
  1. 1. The curved path of a falling object after it is given an initial forward velocity
  2. 3. Acts in the opposite direction of gravity and reduces acceleration
  3. 4. The tendency of an object to resist a change in its motion
  4. 6. The force of gravity acting on an object
  5. 10. Newton's law that says whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object
  6. 12. When the forces on an object are _, the net forces is zero and there is no change in the object's motion
  7. 15. The attractive force that acts between two masses
  8. 16. The _ force is the overall force acting on an object after all the forces are combined
  9. 18. The force that causes a 1kg mass to accelerate at a rate of 1 meter per second each second
  10. 20. A measure of the inertia of an object
