Across
  1. 2. - when gravity is the only force acting on an object
  2. 4. law that states if no external force acts on a group of objects, their total momentum will not change
  3. 8. - the force exerted toward the center of a curved path
  4. 10. one of Newton's laws of motion that states an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a force
  5. 11. - the tendency of an object to resist any change in its motion
  6. 13. - a region of space that has a physical quantity (such as force) at every point
  7. 14. - the gravitational force exerted on an object
  8. 15. - the distance an object travels per unit of time
  9. 19. - a push or pull exerted on an object
  10. 20. - the rate of change of velocity
Down
  1. 1. - the distance and direction of an object’s change in position
  2. 3. - a change in an object's position relative to a reference point
  3. 5. - attractive force between two objects that depends on the masses of the objects and the distance between them
  4. 6. - the friction-like force that opposes the motion of objects that move through the air
  5. 7. - the speed of an object and the direction of its motion
  6. 9. - the maximum speed an object will reach when falling through a substance, such as air
  7. 10. - force that opposes the sliding motion between two touching surfaces
  8. 12. - sum of all the forces acting on an object
  9. 16. one of Newton's laws of motion that states force = mass x acceleration
  10. 17. - “p”, the product of an object's mass and velocity
  11. 18. one of Newton's laws of motion that states for every action, there is an equal and opposite reaction
