错误认识一:浮力的大小与物体的密度有关验证实验:器材:弹簧测力计、规格为2cm×5cm×10cm的长方体铁块和铜块各1块、水、烧杯。实验装置如图1所示。实验数据:①用弹簧测力计测出铁块
Misconception 1: The size of the buoyancy is related to the density of the object Verification experiment: Equipment: spring dynamometer, a rectangular parallelepiped iron block with a size of 2 cm × 5 cm × 10 cm and a copper block, water and a beaker. The experimental setup is shown in Figure 1. Experimental data: ① measured with a spring dynamometer iron
