Newton’s tube Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12755
The Newton’s Tube by Educational Instrument India is a classic physics laboratory apparatus designed to demonstrate the effect of air resistance on falling bodies. It is widely used in school science laboratories, college physics labs, STEM classrooms, and educational training institutes.
This apparatus helps students understand that, in the absence of air resistance, objects of different masses fall at the same rate under gravity. The tube generally contains a light object such as a feather and a heavier object such as a coin or metal piece. When air is present inside the tube, the heavier object falls faster due to less air resistance. After removing the air with a vacuum pump, both objects fall together, clearly showing the principle of free fall in vacuum.
Newton’s Tube is an excellent teaching aid for demonstrating gravity, free fall, air resistance, vacuum, and motion under gravitational acceleration. Its transparent design allows students to clearly observe the experiment, making it ideal for classroom demonstrations and practical physics learning.

How to Use
Place Newton’s Tube on a clean, dry, and stable laboratory table.
Check that the feather, coin, or falling objects are inside the tube.
Hold the tube vertically and allow the objects to fall in normal air.
Observe that the heavier object falls faster due to air resistance acting on the lighter object.
Connect the tube valve or outlet to a suitable vacuum pump using rubber vacuum tubing.
Remove air from the tube carefully using the vacuum pump.
Close the valve after sufficient air is removed.
Again hold the tube vertically and invert it to allow the objects to fall.
Observe that both objects fall almost together in the vacuum condition.
Explain that without air resistance, all objects fall with the same acceleration due to gravity.
After the demonstration, release the vacuum slowly and store the apparatus safely.

Frequently Asked Questions
- What is Newton’s Tube used for?
Newton’s Tube is used to demonstrate that objects of different masses fall at the same rate in a vacuum when air resistance is removed.
- What objects are commonly used inside Newton’s Tube?
A feather and a coin or similar light and heavy objects are commonly used to compare falling motion in air and vacuum.
- Why does the feather fall slower in air?
The feather falls slower in air because air resistance acts more strongly on it due to its larger surface area and lower weight.
- What happens when air is removed from Newton’s Tube?
When air is removed, air resistance is greatly reduced, and both the feather and coin fall together at nearly the same rate.
- Does Newton’s Tube require a vacuum pump?
Yes, a suitable vacuum pump is required to remove air from the tube for the vacuum demonstration.
- Is this apparatus suitable for school laboratories?
Yes, it is suitable for school science labs, college physics labs, STEM classrooms, and educational institutions.
- Which physics concept does Newton’s Tube demonstrate?
It demonstrates gravity, free fall, air resistance, vacuum, and acceleration due to gravity.
- What safety precautions should be followed?
Handle the tube carefully, especially if it is made of glass. Use the apparatus on a stable surface, connect the vacuum pump properly, and release the vacuum slowly after use.
