Centripetal force verification device

The invention relates to the field of teaching equipment, in particular to a centripetal force verification device. 'Centripetal force' is a required course of the modern physics subject, is related in junior high school, is studied deeply in senior high school, and is also a research focus in university. In physics teaching, compared with spoon-feeding type teaching, students can understand and grasp learned knowledge more profoundly through experimental research type teaching, the students can fully participate in experiments, and each learning group can measure to obtain different experiment data and conducts calculating and verification according to the measured experiment data. The centripetal force verification device has the characteristics of easy operation, clear force analysis and accurate measurement, comparison and verification can be conducted through multiple experiments in a classroom, thus the students more quickly know about and grasp the focus and the difficulty related to the centripetal fo
