First use a dynamometer to measure the gravity g1 of the plastic bucket and the cylinder hanging under the plastic bucket, then add water to the transparent overflow cup to the water outlet, hanging the plastic bucket on the dynamometer, and then Put the cylinder into the transparent overflow cup so that the water in the transparent overflow cup flows from the water outlet to the measuring cylinder. At this time, the dynamometer can see the gravity , and the buoyancy , and then see the connection in the measuring cylinder. To the volume of water V1, calculate the gravity of the volume of water V1, Fg= should be obtained by archimedes' principle. Features - Color: Assorted color. - Material: Plastic. - Size: 18.50 x 3.50 x 2.00cm/ 7.27 x 1.38 x 0.79 inch. - Archimedes principle experimenter is mainly used in middle school physics teaching. - To explore the relationship between buoyancy and the water discharged. - This product is mainly composed of transparent overflow cup, measuring tube, plastic bucket, cylindrical cup, and dynamometer. - Be careful not to rub hard objects when doing experiments in plastics to avoid leaving traces. - Used in archimedes principle model to explain and calculate archimedes principle. Package list: 1 set x archimedes principle equipments
