The Centripetal Force Apparatus allows you to investigate the relationship between centripetal force, angular velocity, mass, and radius.

Description

A force sensor measures the centripetal force exerted on a mass as it moves in a circle. A photogate can be used to measure the angular speed. Different masses can be added to the platform and positioned at variable radii. The platform can be driven by a falling mass. The apparatus also accommodates the Vernier Wireless Dynamic Sensor System to measure force, which provides the best set of data. Sensors are sold separately.

Teacher Review

“As an experimental physicist who teaches introductory physics, I strongly recommend Vernier’s new Centripetal Force Apparatus. It is extremely well thought out and engineered.”

Sample Data

This graph shows the tension force in the restraining string (that is, the centripetal force) as a function of the square of the angular velocity of the system. Data were collected by giving the armature a spin, and then allowing it to slow down. Since angular velocity squared is on the horizontal axis, the slope is the product of the mass and radius of the spinning test mass. The three traces correspond to three different masses.
