  4. 10. push or pull
  5. 14. the change in objects motion will depends on the mass of the object and the force exerted

Down
  1. 1. the unit of measurement used for measuring the net force of an object
  2. 2. an object in motion will stay in motion an object at rest will sty arest until an outside force acts upon it
  3. 3. an object in motion will stay in motion an object at rest will stay at rest until an outside force acts upon it this is also known as inertia
