Something won’t move unless something else moves it.

8. What is Newton’s Second law of motion?
Bigger it is the more force needed. The smaller it is the less force is needed.

19. What is Ground Friction?
Friction caused by an object as it travels over the ground.

20. What is Air Resistance?
Friction caused by an object against the sir as it travels.
