SHORT ANSWER
16. The direction of free-fall acceleration is negative because the object accelerates toward Earth (the usual choice of coordinates uses positive as the direction away from Earth).
17. With air resistance, a projectile slows down as it collides with air particles. Therefore, the true path of a projectile would not be a parabola.
18. The natural condition for a moving object is to remain in motion once it has been set in motion.
19. 0.0 N
20. SF is the vector sum of external forces acting on the object.
21. An object with smaller mass has less inertia, or tendency to maintain velocity, than does an object with greater mass.
