  5. 8. an object when thrown
  6. 9. When an object starts to move it is due to _________ _______, or how the forces are no longer balanced.
  7. 11. Wheel+_____ helps an object roll.
  8. 12. ______+ axle is used on multiple types of vehicles.
  9. 15. Ramp, used to decrease force by increasing distance
  10. 17. a machine that can make work easier by increasing the distance and decreasing the amount of force used.
