Plastic Spherical Ball with Metal Screw
Product Code : JL-LEP-10139
The Plastic Spherical Ball with Metal Screw (SKU JL-LEP-10139) is used as a free fall object in the free fall activity of a school physics laboratory. It has a diameter of 25 mm. Because it is a plastic ball with metal screw, the solenoid electromagnet can hold it at the release point, like the steel ball in the same set. Students drop and time both balls to compare how objects of different material fall. JaincoLab manufactures it in India, made as per DepEd guidelines.
Specifications
The ball is specified by its build, size and role: it is a plastic sphere with a metal screw, 25 mm in diameter, used as a falling object in the free fall activity, made as per DepEd guidelines and listed under SKU JL-LEP-10139.

Applications of the plastic ball with metal screw
The ball is used alongside the steel ball whenever the free fall set is run, so that the fall of two different objects can be measured under the same conditions. Typical school physics uses are:
- Timing the fall of the plastic ball from measured heights
- Comparing its time of fall with that of the 12.7 mm steel ball
- Discussing the effect of material and size on falling objects
- Repeating trials to check the consistency of timing

Frequently asked questions
What size is the Plastic Spherical Ball with Metal Screw?
It has a diameter of 25 mm.
Why does the plastic ball have a metal screw?
The metal screw allows the solenoid assembly, which acts as an electromagnet, to hold the ball before release.
How is it used with the steel ball?
Both are used as free fall objects in the same activity, so students can compare their times of fall.
What should a quotation request include?
Send the SKU JL-LEP-10139, the number of balls, any other free fall parts you need and the delivery destination.
