Why do rafts float?
When an object enters water, two forces act upon it. … An object will float if the gravitational (downward) force is less than the buoyancy (upward) force. So, in other words, an object will float if it weighs less than the amount of water it displaces. This explains why a rock will sink while a huge boat will float.
Why do wooden rafts float?
Wood’s density is lower than that of water, so a wooden boat will float on the water. Ships are typically made of metal, which is denser than water, and therefore air-filled buoyancy chambers are built into them. This makes the ship less dense than the volume of water it occupies, thus enabling it to float.
