Universal Gravity Experiment UG　C15-3202

It is an experimental instrument that directly verifies the law of gravitation by observing how large and small lead spheres attract each other and determining the constant of gravitation.
Although the force applied to the lead spheres is weak, of the order of 10^-9, it can be detected as the movement of the projection point of about 1.6° (about 3 cm when projected to a point 1 m from the mirror) by reflecting the laser beam to the mirror mounted only in torsion.

NARIKA

Face pushing force experimenter (brick type)　C15-3305

Seventh Grade Force and Pressure (Pressure Sponge Experiment) The amount of pressure varies depending on which side of the brick you place on the sponge.
The difference in pressure is experimentally observed by measuring the amount of indentation of the sponge.
