BIO PHYSICS Quiz: PhET Buoyancy
Document Summary
To determine if a pair of blocks will float or sink, we need to know the density of the both liquid and the object. If the object is less dense than the liquid, it will float. If the object is denser than the liquid, it will sink. Another factor is the shape of the object. In the experiment, although both of the blocks had the same weight, one block sank, and the other floated. Furthermore, the overall volume of the block that floated is larger which means that it has a great deal of space, and the other block doesn"t. The two blocks will only sink if it will have the same volume, with the brick (heavier) on top of the wooden block (lighter): explain the forces" interaction and explain why an object floats or sinks. The floating and sinking tendency of the two blocks is affected by the force acting on them.
