Introduction

The PASCO SE-9788 Coin and Feather Tube

demonstrates the effect due to gravity on objects

falling through a vacuum, compared to the effect on

objects falling through air.

In the demonstration, students see that in an

environment in which air resistance is not

countering the force of gravity (in a vacuum), any

object— regardless of its mass or density—will

require the same time period to reach the bottom of

the tube. However, when air molecules are present,

air resistance counters the force due to gravity.

Students will observe that when air is present,

objects of differing mass or density require

differing time periods to reach the bottom of the

tube.
