15. change in velocity over a period of time.
16. The tendency of any object with mass to resist changes in velocity.
17. an object in motion tends to stay in ________ unless acted upon by a force?
19. Which of Newtons Laws of Motion is know as the law of inertia?

1. SI Unit used to measure Force.
2. imaginary point where mass is evenly distributed on all sides around it.
4. Force that pulls object towards each other.
5. the vector sum of all the forces that act upon an object, taking into account the fact that two forces of equal magnitude and opposite direction will cancel each other out.
7. - A push or pull which, if unopposed, will cause an object to accelerate
