Given Statement: "In free-fall the acceleration is always g and always straight downward regardless of the motion."
Three Objections:
(a) If I drop a balloon or a feather, it doesn't fall nearly as fast as a brick.
(b) Not everything falls straight down; if I throw a ball it can go sideways.
(c) If I hold a wooden ball in one hand an a steel ball in the other, I can tell that the steel ball is being pulled down much more strongly than the wooden one. It will probably fall faster.
How would you respond to these statements? Discuss the extent to which these invalidate the quoted statement. If they don't, explain why
