Answers the Question- Do heavier objects fall faster than lighter objects?
Easy to set up and economically priced, our Coin & Feather Demo can be used to perform the classic experiment of a lighter object falling at the same rate as a heavier object when air resistance is removed from the equation. The demo includes a metal disk, a feather and a transparent free fall tube. The tube easily mounts on a ring stand or can be held by a student. The acrylic tube is 91 cm long and 5.5 cm in diameter and is equipped with an evacuating valve. Any standard vacuum pump can be attached, or use our hand-held vacuum pump.
The Coin & Feather works with any standard vacuum pump (Hand-Held Vacuum Pump P1-5201) but we recommend our (Electric Vacuum Pump P7-6502).
*Note: with the hand-held vacuum pump, you may not achieve a full vacuum, but the effect of the lowered air pressure will still be noticeable.
