United Scientific Spring Scale Centripetal Force Apparatus – Physics Lab Demonstration Tool with 5 N Scale & Activity Guide

Explore the fundamentals of circular motion with the United Scientific Spring Scale Centripetal Force Apparatus, designed to provide students with a dynamic and hands-on physics learning experience. This simple yet powerful tool allows learners to visualize how centripetal force varies as they change the radius or spin velocity of a rotating mass.

Holding the white handle, students rotate the rubber stopper overhead, creating tension in the string that connects to the easy-to-read 5 N spring scale. As spin speed increases, the spring scale clearly displays the changing force, offering immediate insight into the relationships between force, distance, and velocity.

This educational apparatus includes:

A 24-inch adjustable cord for variable radius configurations

A clear 5 N spring scale for accurate force measurement

A detailed activity guide for structured classroom or lab use

Ideal for physics classes, STEM labs, and hands-on demonstrations, this spring scale apparatus turns abstract physics principles into tangible discovery tools.
