Atwood machine Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12707
The Atwood Machine by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate Newton’s laws of motion, acceleration, tension, mass difference, and uniformly accelerated motion. It is commonly used in school physics laboratories, college science labs, STEM classrooms, and educational training institutes for mechanics experiments.
The apparatus generally consists of a pulley system with two masses connected by a light string. When unequal masses are attached on both sides of the pulley, the system moves due to the difference in weight. This helps students observe and calculate acceleration, tension in the string, and the relationship between force and motion.
Key Features

Useful for demonstrating tension, mass difference, and force balance.
Helps students understand uniformly accelerated motion practically.
Suitable for school, college, and STEM physics laboratories.
Can be used with stopwatch, digital timer, or motion sensor depending on setup.
Simple construction for easy classroom demonstration.
Durable laboratory-grade design for repeated educational use.

How to Use Atwood Machine
Place the Atwood Machine on a flat, stable, and dry laboratory table.
Fix the pulley securely at the top of the support stand.
Pass the string over the pulley and attach mass hangers to both ends of the string.
Add equal masses first to check balance and smooth pulley movement.
Add a small extra mass to one side to create a difference in weight.
Release the masses gently and observe the motion of the system.
Use a stopwatch, digital timer, or motion sensor to record the time taken for a measured distance.
Calculate acceleration and compare the experimental value with theoretical results.
Repeat the experiment with different mass combinations to study the effect on acceleration.
After use, remove the weights carefully and store all components safely.
Educational Applications
The Atwood Machine is widely used in physics laboratories to teach mechanics and Newtonian motion. It helps students understand how an unbalanced force causes acceleration and how tension acts in a string over a pulley. This apparatus is useful for experiments on Newton’s second law, acceleration due to gravity, pulley systems, force analysis, and mass-dependent motion.
