Yes, but density is a pretty good proxy for how low the air resistance will be. Not perfect, but good. (View Post)

Dinner at 10pm in Spain is partly a function of its time zone. Spain is (on average) west of England, but its timezone is east of England. So the sun rises and sets at a very late local time compared… (View Post)

Hm. Fairly sure a sand filled box will reach a faster terminal velocity. Got it, I think. This is because the force on the box is directly proportional to the box's weight. Thus there is a much … (View Post)

In a vacuum, no. In air, yes - because the upward force of air resistance increases as you go faster until it is equal to the force of gravity. This is called terminal velocity. At this point, you do… (View Post)
