Conservation of Angular Momentum Manufacturer,Supplier and Exporter in India
Product Code : JA-ELA-5514
The Conservation of Angular Momentum apparatus (SKU JA-ELA-5514) is a demonstration unit supplied by JaincoLab for showing what happens to a spinning body when its mass is drawn towards the axis. A vertical board carries a rotating arm on which two weights can be slid by a pull cord. With the weights at the outer ends of their travel the arm is spun by hand; pulling the cord draws the weights to the centre, and the arm spins markedly faster. It is the same effect an ice skater uses in a pirouette.
Specifications
The unit is intended for visual demonstration only; no measurements are made with it.

What students observe
Because angular momentum is conserved, reducing the radius of the rotating masses reduces the moment of inertia and the angular velocity rises to compensate.
- Spin-up of the arm as the weights are pulled inwards
- The link between moment of inertia and angular velocity
- A laboratory version of the ice-skater pirouette
Scope of supply and ordering
The unit is supplied by JaincoLab with its instruction manual.
Frequently asked questions
Does the apparatus take measurements?
No. It is for visual demonstration of the principle only.
How are the weights moved during a spin?
A pull cord draws them from the outer ends of the arm towards the centre of rotation.
