Item Type: Buoyancy Experiment Equipment Material: Metal + plastic Model: J21007 Purpose: Teaching equipment How to Use: First use the dynamometer to measure the gravity g1 of the plastic bucket and the cylinder hanging under the bucket, then add water to the water outlet in the transparent cup, hang the plastic bucket on the dynamometer, and then place the cylinder on the transparent Go into the cup and make the water in the transparent cup flows from the water outlet to the measuring cylinder. At this time, the dynamometer can see the gravity g2, and the buoyancy is F, and then see the volume V1 of the water received in the measuring cylinder, calculate The gravity g3 of the volume of V1 water is F float = g3 based on Archimedes' principle. Then verify, pour the water in the measuring cylinder into a plastic bucket, and put the cylinder in a transparent cup of water. The gravity measured on the dynamometer should be g1.
