1. Boat floats because there is a force that is pushing it up.
2. Only the weight of the object determines if the object will sink or float.
3. If I change the shape of the clay, its weight and volume also change.
4. Cutting a wood in half will also make its density half of the original density.
5. The pressure exerted by the fluid at rest on an object is directly proportional to the density of the liquid
and depth and is sometimes called as gauge pressure.
