Question

Suppose you had a feather, an orange, and a watermelon. Which of the following describes how quickly each of the objects will fall without air resistance, relative to the other two?
a. All three objects will fall at the same rate.
b. The watermelon will fall faster than the other two.
c. The orange will fall the fastest, followed by the watermelon and then the feather.
d. The feather will fall faster than the orange, which will fall faster than the watermelon.

Answer 1

WITHOUT air resistance . . . like on the moon, or in a tank with all
the air removed from it . . . a feather, an orange, and a watermelon
will all fall at the same rate. 

So will a piece of tissue, a mosquito, school bus, a rock, and a cruise
ship. 

If you drop them all at the same time, then they will all hit the ground
at the same time.
