Newton’s tube Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12755
Quick Answer: Newton’s Tube is a transparent tube that shows how air resistance affects falling bodies. With air inside, a light object such as a feather falls more slowly than a coin; once a vacuum pump removes the air, both fall together.

About This Product
The tube is a standard demonstration of free fall: it lets a class compare the same drop in air and in a near-vacuum. It supports lessons on gravity, air resistance and the idea that, without air, bodies of different mass fall with the same acceleration. Educational Instrument can arrange export supply of the Newton’s tube to Slovenia, Argentina, Ecuador, Oman, Mauritius and Belgium.
Frequently Asked Questions
Why do the feather and coin fall together after the air is removed?
Without air resistance, all objects fall with the same acceleration due to gravity, so the light and heavy objects reach the bottom almost together.
