EM-119 | Centripital Force Apparatus

Technical Specification
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 or Force and Acceleration Sensor to measure force, which provides the best set of data.
This apparatus include the necessary sensors. Here are sensors and combinations of sensors that can be used:
  1. Dual-Range Force Sensor 
The Dual-Range Force Sensor is a general-purpose sensor for measuring pushing and pulling forces. Two ranges allow you to measure forces as small as 0.01 newtons and as large as 50 newtons.
  • ± 10 N Range Resolution: 0.01 N
  • ± 50 N Range Resolution: 0.05 N
  1. Photogate
Photogates allow for extremely accurate timing of events within physics experiments, for studying free fall, air track collisions, pendulum periods, the speed of a rolling object, among other things. The Vernier Photogate includes an accessory rod for mounting to a ring stand.
