S77-1321-W0
easure speed and acceleration in an instant with the BeeSpi v.
Unlike traditional tape-based velocity measuring experimentthat is hard to set up and can be inaccurate, BeeSpi v uses
advanced light gate technology to measure speed of an object in notime, based on which you can easily calculate acceleration of object
by using multiple BeeSpi vs. This provides additional class time toanalyze the results of the experiment, as well as, helps the students
improve their understanding.

T

his equipment is the most suitable for dynamics experiment of sphere（ball）rolling down a track incombination with a BeeSpi v attached as velocity measuring gate for the sphere.

This helps learning;
1. Corelation of height and speed.
2. Corealtion of impact force to an object and height/speed/weight.
（1）The angle of slope is adjustable from 0 to 45 degrees,
which is measurable with a protractor on one side of the track.
（2）With the scale beside the track, you can measure thedistance of objects moved by the impact.
（3）If a BeeSpi v is set on the track, you get the velocity ofsphere directly.
