Stopper Fork Assembly
Product Code : JL-LEP-10152
The Stopper Fork Assembly (SKU JL-LEP-10152) is the low-inertia string guide of the Newton's second law of motion experiment. The stopper fork assembly leads the thin string from the dynamics cart down to the hanging driving mass, so that the pull of the mass reaches the cart with very little of the force being used to turn the guide itself. JaincoLab manufactures it in India as part of its dynamics cart and rail apparatus for school physics laboratories.
Specifications
The stopper fork assembly is a string guide with low inertia, used in Newton's second law of motion experiment to carry the string from the cart to the driving mass; it is listed under SKU JL-LEP-10152 and works with the thin string and the 3 gram driving masses of the same set.

Applications of the stopper fork assembly
The assembly is used at the point where the string leaves the rail, so that the weight of the driving mass is turned into a horizontal pull on the cart with as little loss as possible. In school mechanics practicals it is used for:
- Guiding the thin string between the dynamics cart and the hanging driving mass
- Keeping guide-related error small in force, mass and acceleration measurements
- Repeating runs with different numbers of driving masses
- Replacing the string guide of an existing dynamics cart set
Scope of supply and ordering
The listing covers one stopper fork assembly as described in the specification table. String, driving masses, carts and rails are separate catalogue items; accessories, spares and quantities are confirmed on the quotation.
Minimum order quantity, lead time and packing are confirmed on the quotation for the number of assemblies and the delivery destination. JaincoLab supplies single schools, bulk college orders and education projects, and exports to Africa, the Middle East and South and South-East Asia.
Frequently asked questions
What does the stopper fork assembly do?
It acts as a low-inertia string guide in Newton's second law of motion experiment.
Which parts is it used with?
It guides the thin string that connects the dynamics cart to the 3 gram driving masses.
Why does low inertia matter?
Less of the driving force is used to move the guide, so more of it reaches the cart being measured.
