Thank you very much for purchasing this product.
Be sure to read this instruction manual before using it.

This product is used for “experiments for checking the movement of a weight rolling on a slope”.
We can call it Weight Collision Test Apparatus or I-Gauge. It can easily change the height of point
to release the rolling weight (i.e., inclination of a slope) or the mass of the weight. It enables
collision experiments under stable conditions, since the rail on which the weight rolls down
smoothly changes a slope angle or even get into a almost horizontal position.
The advanced model OS-KB allows enhanced collision experiments while measuring the collision
speed using the BeeSpi v (speed measurement device) supplied with the product.
・Do not store the product in a dusty, humid, or hot place.
・Do not use or leave the product in a place exposed to strong direct sunlight, a car under the burning sun, or a hot
place. Otherwise, it may deform or become defective.
・Do not make an experiment on an unstable table or on an inclined surface.
・Do not expose the product to a strong impact or throw it.

[PREPARATION]
(i) Attach the angle adjusting plate to the body by the fixing screws.
Fit the bottom and secure the plate firmly to avoid misalignment.
(ii) Insert the two gates at the gate positions shown in
the illustration in [SPECIFICATIONS] above. Be
careful not to bend the gates.
(iii)Insert the footing of BeeSpi V into the rail as shown on the picture below. If you purchased the
OS-KB. Apply the BeeSpi V to the rail and push it firmly until it is securely attached.
(iv) The sliding body for collision experiments is to be put on the rail on the body, between the gates.
It is a grooved plastic body sliding on the rail that has two grooves that fit the rails. Place it so
that these grooves are right on the rails.

[USAGE]
This product is designed for collision experiments between a weight (ball) rolling down on a slope
and the sliding body that is placed beyond the gate. Experiments are conducted by making a weight
rolling down on a slope by colliding with the sliding body at the gate. Because the gate is used to
stop the weight at the moment of collision the weight collides with the sliding body only once.
(i) Loosen the fixing screw of the angle adjusting plate and move the slope base to the intended
angle. Fix the angle adjusting plate with the fixing
screw firmly, so that the slope will not move.
(ii) Set the sliding body for collision experiments at the 0cm
position of the scale (touching the gate).
(iii)Select either of the steel ball or the porcelain ball and
use it for an experiment.
(iv) Drop the steel ball or porcelain ball from the highest
position of the rail on the slope base.
* When using the BeeSpi V, turn on the switch to place
the product in standby for measurements. (For details,
refer to the manual of BeeSpi V.)
(v) Record the distance the sliding body moved when the weight collided with it. Modify the way of
measurement based on the experiment conditions.
[EXPERIMENT CONDITION EXAMPLES]
●Changing the rail height
Measure the height of the point to drop the weight with a scale and conduct experiments while
changing the height.
●Changing the mass of the weight
Check the difference in the results of using the supplied steel ball and the porcelain ball.
●Changing the inclination of the slope (0° to 45°)
Change the inclination of the slope by adjusting the angle of the slope base and check the
results.
