Chapter 384: Going Through the Back Door

The question is even more simple now," Yue Feng answered, "This can also be explained using the theory above, different materials definitely have different densities.

Anyone who has studied junior high physics knows that the buoyancy of an object in water is equal to the weight of the water displaced.

For two objects of the same volume, ignoring their own weight, the buoyancy they experience in water is the same, but the weights of objects with different densities are not the same—after deducting their own weight, the remaining buoyancy will vary in magnitude.

To achieve the same amount of lead needed, the volumes of fishing floats made from different materials must be different. This circles back to the old issue: the ones with a smaller overall volume and smaller cross-sectional area are more sensitive, which does not contradict what I said before."
