Product Information
PSAW Laboratory Equipments Physics / Air Resistance DemonstrationNewton’s Tube Apparatus for Physics Laboratory
A transparent glass tube apparatus for physics demonstrations involving falling objects and the effect of air resistance. The specified assembly includes a closed end, a sealed lid with tap and air outlet connection, plus a wedge, sponge and a small metal ball.
Tube Diameter 30–100 mmMinimum Tube Length 1,500 mmMetal Ball Diameter 5 mmPurpose of the Newton’s Tube Experiment
Understanding falling objects and the influence of air
Newton’s Tube is a physics demonstration apparatus designed to help learners investigate how air affects the motion of objects. In an appropriate experiment, a transparent tube can be used to observe falling objects under normal air conditions and, if the apparatus and vacuum equipment support it, under reduced air pressure.
The supplied configuration described here includes a transparent glass tube, one closed end, a sealed lid with a tap and air outlet connection, a wedge, a piece of sponge and a metal ball with a 5 mm external diameter. The exact function of each supplied accessory should be confirmed against the manufacturer's instructions.
Quick product answer: This Newton’s Tube has a diameter range of 30–100 mm and a minimum length of 1,500 mm. Its sealed lid includes a tap and air outlet connection. The specified accessories are a wedge, sponge and 5 mm external-diameter metal ball.Apparatus Construction
Illustrative component arrangement
Schematic only. Confirm the actual position of the tap, accessories and closures from the product photograph or manufacturer's instructions.
How the Demonstration Can Be Conducted
General experiment pathway — follow the supplied apparatus instructions
01 / PREPARE Inspect the Tube
Check the glass body, closed end, sealed lid, tap and air outlet for damage or leaks.
02 / SET UP Prepare the Objects
Use only the specified accessories and follow the supplier's instructions for placement.
03 / OBSERVE Compare Motion
Observe object movement under the experiment's prescribed air conditions and record findings.
Safety: This is a long glass apparatus. Secure it appropriately, protect it from impact, and use compatible vacuum equipment only if the tube is specifically rated for that operation. Do not apply vacuum or pressure based solely on the presence of a tap or air outlet.Technical Specification Sheet

Air Resistance
Air resistance is a force that opposes an object's motion through air. Its effect depends on factors such as shape, speed and surface area.
- Compare how objects move through air.
- Discuss drag and falling motion.
- Relate observations to experimental conditions.
Free Fall and Gravity
In ideal free fall, gravity causes objects to accelerate independently of their mass. In air, drag can make their observed motion differ.
- Introduce gravitational acceleration.
- Discuss ideal and real experimental conditions.
- Understand why controlled experiments matter.
